There's a lot of people missing the point of this video. It doesn't matter where you put your disconnect switch. He put his where he wanted it. Perhaps it was the easiest way to do it or the most simplest way. It works that's all that matters. You can take the knowledge he is giving you and you can put the switch any place you want. Give the guy some slack he's showing some people out there who don't have the knowledge to understand how to simply fix their battery drain problem, or possibly can't afford a mechanic to do it for them. I'm a mechanic and I have done the same thing on the cranes where I work.
I use to drive truck as part of my job. Dump trucks, semi trucks, etc. This type of switch was mandatory. Every night, flip it off. Back on in the morning. Its also great for theft prevention if you hide it. Thats why I'm here. Someone stole my wife's 96 Bronco, tweaked on it for a couple days, then ran out of gas and abandoned it. They got the doors and tried to prybar off the shell. We got it back, but im not even hooking up the battery until I get one of these on it.
thought he was polish for a moment there. lol on a serious note there are automatic kill switches that kill after a 3-5minute power down if you want to install one that will run on its own.
I'm buying a 2002 Pathfinder that has the same electrical problem draining the battery. My mechanic told me he can put in a kill-switch so it's good to know that this can save your battery and Theft.
Thanks for this video man. Just went through my 2nd brand new battery for my old band van, and spring and summer is super busy for us. Moneys always tight; this should do the trick.
I watched your video over a year ago, installed the kill switch and I can’t thank you enough brother 🙌 Thanks for the knowledge 💯 I also got my kill switch through my hood on the driver side, SUPER CONVENIENT in my opinion 🤙
This has been a saving grace. I bought a 98 Grand Cherokee with the same issue. Noticed the cab lights were still getting a current even with a dead battery. Removed em; had it cranking for a few days but now it absolutely won't hold a charge. Gonna invest in this and a jump box next 👍

Definitely want the switch on while jumping, don't need it on if only charging the battery. I like the switch on the exterior because I don't want to be opening the hood everytime I get out or leave the vehicle.

Correct but the reality it's about 2 ft of distance in length from the battery do it doesn't affect anything. What your referring to is large distances.

I’d check your alternator bro. Draining of a battery over the course of 1 day of sitting usually means your alternator is starting to give out. I have this issue with my Mazda3. Haven’t gotten around to rebuilding or purchasing a new one yet. I just start my car up when I get home if I don’t use it & run it for about 5 minutes. My alt is only running at just over 50% efficiency. Just a heads up before you start going thru battery after battery.
This is true to a point. If your alternator is going bad you would experience some other signs too, like: when driving at night, lights and instrument panel would be dim. Also if you drive for more than 15-20 min. with lights, radio and any other electronics, your vehicle will just die on you! The alternator is responsible for providing electricity to all electronics once vehicle is running,(not the battery) if it's going bad it will leave you stranded! Especially at night, because that's when you run every light and more likely to leave you stranded. Once a vehicle is running you can remove the battery and it will still run, as long as you do not turn it off;[ that's where the battery comes into play; It's only there to crank the car, that is it!
@Mike Meshel alternator was not the issue when I did this project, it's a constant drain from either the anti theft not going to sleep or the air suspension constantlly leveling the vehicle
@@carlosthemasteroftrades5070 cool,it can be a pain trying to figure out that kind of drain,I don't like paying a shop to drain my pockets either,thanks for the vid,I enjoyed watching.
Showing how you run the cables from the Neg side of the battery to the switch , that's it , that would have done it ,, it worked great, you have two cables running from the battery to the switch please show the hook up on that,, thank - you.
It is really one cable. It ties in at the old battery terminal (not attached to the battery runs to the kill switch and returns back to the new battery terminal now connected to the battery. I will make an electrical schematic and try to attach it somehow.
I need to do this to a zero turn that costs a lot to find the drain, so we are doing this instead of replacing the battery every time we use it. We have a different one but it’s always nice to have a backup in case someone needs to borrow it or our main one is waiting on parts
This has saved my battery for years now. Still have the same battery as when I installed the kill switch. Thanks for the comment, don't forget to like, share and subscribe.
Hi, have a question, what you do in snow or rain and you have to drive a car? Water goes while the cap is open and key is in! Actually I fixed this in my Hyundai Sonata 2009 but not on the hood, I drilled next to the Wiper and somehow managed to fix there, what I do while snowy or rainy weather just put a zip lock bag on it and a rubber band around it while driving.
Honestly I don't think it would hurt anything. The key is all plastic with a metal rod to make the connection when turned. Also the little bid of moisture that would fit in there would just evaporate as the hood warms up. Mine has been on , for over a year and has been through it's fair share of snow, rain, mud, sand and salt, with no issues!
Good video. I have an old 1990 Ford Ranger. Thirty years old and this is the only issue, I’d say that’s a good deal. Built Ford Tough! Anyway, I was having the same issue. Checked the truck, all lights go off, radio, and everything I could possibly check. Thought it might be an alternator problem, pretty common stuff. Anyway, took a volt-inator I guess it’s called, neat little tool to check the voltage. The truck charges when it’s on, and it will receive a charge when off. But something was draining the battery really slowly. Any ideas? Could it just be a failing alternator? It charges the battery when the truck is running. I’m no professional mechanic though, only seventeen years old and still learning.
Never heard of an alternator draining a battery, even when going bad. So I would remove that as an issue. .maybe something as small as a cigarette lighter draining the battery. This is why I put the kill switch on mine, could not find what was draining battery. Good luck!
@@carlosthemasteroftrades5070 Thanks, I’m gonna need it. I’m no professional. 😂 But I hope to learn a lot of trades. Mechanical, Electrical, and all things as such. We decided to unplug the alternator completely, charge the battery to see if the battery will drain or keep a charge without it. We’re just going through the process of elimination. Thought about pulling some fuses to see if I could find the problem that way somehow. Have a good day, anyway. Thanks for commenting.
I'm 52 and still learning new things every day I hope you keep up with learning how to work on your own vehicles and keep on with the process of elimination and you will find your problem Good luck
So, disconnect the battery terminal and connect the ground coming from the switch to it, tape it together and take another short cable and put in a new terminal ?
Something like that...it's like you cut the cable in half and install the switch in-between those ends that you cut...simple ! Don't forget to like, share and subscribe!
So is both wires from the kill switch running into the negative of the car battery? or is one running to the negative and one is running to the ground wire of the car?
Think of it like this, it's one wire with a brake in the middle to interrupt the feed. One wire, cut in half, with the kill switch connecting them back together.
Great video!! I'm a single mom of three and have zero car experience and wouldn't even attempt this job even though this is what I need with my old car and electrical problems too costly to fix before I get a new one in a few months. So not meaning to sound ignorant, but can I just disconnect my battery manually every time I am done driving? I know it's more work but i have no other options. I just got a new battery and it still dies after a few days, so once I call roadside assistance and get it jumped again, would just taking off the negative bolt each day do the trick? Any other simple solutions or precautions for disconnecting and reconnecting the battery multiple times a day?? Thanks a lot!!
Carlos Vazquez yes AutoZone tested my alternator when I bought the new battery two weeks ago. When I turn the car off the engine fan continues to run for hours sometimes.
The voltage/wattage on the battery is not enough to hurt you. Yes, you may have seen sparks when you touch the negative and the positive. But it won't kill you. Keep flammable things away, like gas or paper,it will ignite. If you just remove the negative you should be fine. Just make sure when you put it back it is very tight. You do not want the cables to be loose, then your battery will not charge. One last note: your battery charges as you drive your vehicle. It takes a lot of power to start your car, and it takes a lot of driving to recharge that battery. So if you do a lot of stop and go driving and do not allow proper time(10-15min.of hwy driving) for the battery to recharge it will not have enough of a charge to start your vehicle. In cold weather batteries drain even faster when not in use. Hope this helps.
Although you want those fans to run after your vehicle is off, to cool off the engine. But after a few minutes they should cut off. Sound like a fan relay or temperature sensor may be keeping those fans on.
I have the same kill switch set up , will it remove a check engine light ?? Wondering because I bought a car with the kill switch like that and I want to remove it but idk if it will cause the check engine to go on
No it will not fix a check engine light. What ever is making light come on ,will eventually make it come back on. You probably haven't seen it , since every time you pull the key to the kill switch; you are resetting the computer, Causing the ecm to restart the troubleshooting process that will eventually find what the issue is, causing the light to come on. If you run the vehicle long enough without pulling the kill switch, the light will come on, if there are issues. Depending on drive habits it could take anywhere from a couple hrs driving to a few days....
Most check engine light issue are caused because of emissions faults or other safety faults. The kill switch will not prevent nor cuase a check engine light to come on.
The only thing am wondering if a vehicle with all this ECU system, if we disconnect for a few days than reconnect will we have to reset or reprogram some electronic system?
I wouldn't think so. For ex.,if battery dies nothing has to be reset... My problem was a shortage,somewhere, making one of the systems work 24/7 and thus draining the battery down.
@@antrinh5525 Actually if you listen to the video, u will hear that I put silicone seal , to keep water out. And if you know anything about electrical systems: there is such a thing as fail safe, they are called fuses!
My absolute last plan would be to drill the hood. I mean why? That chinese rubber cover will dry rot and fall off or get packed under snow. Gravity takes that moisture...down. thing will corrode in no time.
I used either 6GW or 8GW stranded. Because that's what size comes off the original ground terminal in this vehicle. But it all depends on how complicated your electrical system is; I would go with the same or bigger from what the original wire is presently.
So one wire on the kill switch goes to the negative terminal on the battery and the other wire on the kill switch goes to the existing negative battery wire?
I tried it on my Japanese made daihatsu sirion and the switch burned out after a day. I used 8 gauge wires after a while the car won't start and then it started smoking. Now the switch is no good. So am left wondering what the hell did I do wrong? I installed the switch on the dashboard and fished the wires through the firewall. Please advise!
If it's getting hot , you are arching somewhere ,meaning you have a loose connection somewhere or you have a faulty switch. It Should not get hot at all.
Pretty much what you said. Remove terminal from battery, add cable from that removed terminal and run to the 1st terminal of the kill switch. From the 2nd terminal of the kill switch, run cable back to the battery and put on battery where you removed the 1st cable. Now you have a switch to turn on and off.
I was looking for someone to ask if it’s safe to leave my kill switch overnight cause I thought it used battery life but it’s actually a good idea right?
Leaving the kill switch on is like leaving a flash light on.... eventually your batteries will die. The whole point of the kill switch is to KILL the power to your battery, so it does not drain....unless you put a kill switch, for other reasons.....
@@carlosthemasteroftrades5070 I have it for theft prevention so my car doesn’t get stolen when I’m out so I should probably turn it off when I’m home huh
@@jorges3824 Good idea. the other way is make kill switch tru fuel pump relay. Put them together so if you leaved your car in a long time nothing to worry stole it. Thief's cant start the car and no worries about battery drain. two kill switch yeah
IF you have an overnight battery drain you need to figure out WHERE that's coming from. Disconnect is only covering up an underlying issue its not resolving it.
Yes, I don't have a problem with the battery draining anymore. I can leave the vehicle off for weeks and jump right back in it and it will crank back up.
My 2013 peter built lights cut out I shook the harness next to it lights came on next stop same thing checked batteries alternator fuses all good think it's my kill switch
Wow, really? Through your hood? I believe the switch would do better on positive/red wire side. I ran mine through firewall and mounted in dash under steering wheel.
It's a parasitic draw. Use a multi meter to bridge the battery to the terminal pull one fuse Ata time until you see the voltage being drawn drop to 50 milliamps
@@carlosthemasteroftrades5070 ok cause i have a problem with my jeep where if i want my anti theft to go away and my dash and ac work i need to unhook the battery to reset everything and im thinking of puttin a kill switch now my question is
I used a thick wire because my battery is very large. But for a jeep you should not need such thick wire and may be able to pass it through the firewall easier. Just make sure it's not too thin and then you have a chance of it getting hot and maybe even melting or shorting out on you.
Well here I go, I slammed my kill switch in the driver door, I think I Broke it I need to replace the kill switch + put those 2 wire ends for the nuts and bolts the switch. (WISH ME LUCK)
Shit I got a 2003 Ford explorer and the Anti-Theft stuff is messed up in mind I know it wouldn't be the airbags because I wrecked it and not one airbag came on so scratch that

I’d check your alternator bro. Draining of a battery over the course of 1 day of sitting usually means your alternator is starting to give out. I have this issue with my Mazda3. Haven’t gotten around to rebuilding or purchasing a new one yet. I just start my car up when I get home if I don’t use it & run it for about 5 minutes. My alt is only running at just over 50% efficiency. Just a heads up before you start going thru battery after battery.
This is true to a point. If your alternator is going bad you would experience some other signs too, like: when driving at night, lights and instrument panel would be dim. Also if you drive for more than 15-20 min. with lights, radio and any other electronics, your vehicle will just die on you! The alternator is responsible for providing electricity to all electronics once vehicle is running,(not the battery) if it's going bad it will leave you stranded! Especially at night, because that's when you run every light and more likely to leave you stranded. Once a vehicle is running you can remove the battery and it will still run, as long as you do not turn it off;[ that's where the battery comes into play; It's only there to crank the car, that is it!
@@carlosthemasteroftrades5070 not allways,sometimes alternator charges fine but will drain back with bad diode when not runing
@Mike Meshel alternator was not the issue when I did this project, it's a constant drain from either the anti theft not going to sleep or the air suspension constantlly leveling the vehicle
@@carlosthemasteroftrades5070 cool,it can be a pain trying to figure out that kind of drain,I don't like paying a shop to drain my pockets either,thanks for the vid,I enjoyed watching.
Where did you get that specific kill switch
Autozone, Sears, even Harbor Frright , different brands, same switch and key.
Is the wire from the switch put in with the original wire in the negative terminal?
Yes
thanks

What size socket or wrench fits those nuts that hold the wires on?
They come in various sizes, but something like a 1/2 " socket or sizes 10-12mill.
Mantap👍👍👍👍
Showing how you run the cables from the Neg side of the battery to the switch , that's it , that would have done it ,, it worked great, you have two cables running from the battery to the switch please show the hook up on that,, thank - you.
It is really one cable. It ties in at the old battery terminal (not attached to the battery runs to the kill switch and returns back to the new battery terminal now connected to the battery. I will make an electrical schematic and try to attach it somehow.
I need to do this to a zero turn that costs a lot to find the drain, so we are doing this instead of replacing the battery every time we use it. We have a different one but it’s always nice to have a backup in case someone needs to borrow it or our main one is waiting on parts
This has saved my battery for years now. Still have the same battery as when I installed the kill switch. Thanks for the comment, don't forget to like, share and subscribe.
Hi, have a question, what you do in snow or rain and you have to drive a car? Water goes while the cap is open and key is in!
Actually I fixed this in my Hyundai Sonata 2009 but not on the hood, I drilled next to the Wiper and somehow managed to fix there, what I do while snowy or rainy weather just put a zip lock bag on it and a rubber band around it while driving.
Honestly I don't think it would hurt anything. The key is all plastic with a metal rod to make the connection when turned. Also the little bid of moisture that would fit in there would just evaporate as the hood warms up. Mine has been on , for over a year and has been through it's fair share of snow, rain, mud, sand and salt, with no issues!
Good video. I have an old 1990 Ford Ranger. Thirty years old and this is the only issue, I’d say that’s a good deal. Built Ford Tough! Anyway, I was having the same issue. Checked the truck, all lights go off, radio, and everything I could possibly check. Thought it might be an alternator problem, pretty common stuff. Anyway, took a volt-inator I guess it’s called, neat little tool to check the voltage. The truck charges when it’s on, and it will receive a charge when off. But something was draining the battery really slowly. Any ideas? Could it just be a failing alternator? It charges the battery when the truck is running. I’m no professional mechanic though, only seventeen years old and still learning.
The tool is a voltmeter, we call it a voltinator here. 😂 No clue why.
Never heard of an alternator draining a battery, even when going bad. So I would remove that as an issue. .maybe something as small as a cigarette lighter draining the battery. This is why I put the kill switch on mine, could not find what was draining battery. Good luck!
@@carlosthemasteroftrades5070 Thanks, I’m gonna need it. I’m no professional. 😂 But I hope to learn a lot of trades. Mechanical, Electrical, and all things as such. We decided to unplug the alternator completely, charge the battery to see if the battery will drain or keep a charge without it. We’re just going through the process of elimination. Thought about pulling some fuses to see if I could find the problem that way somehow. Have a good day, anyway. Thanks for commenting.
I'm 52 and still learning new things every day I hope you keep up with learning how to work on your own vehicles and keep on with the process of elimination and you will find your problem
Good luck
Best to have the right gage also

So, disconnect the battery terminal and connect the ground coming from the switch to it, tape it together and take another short cable and put in a new terminal ?
Something like that...it's like you cut the cable in half and install the switch in-between those ends that you cut...simple !

Very helpfully, but i think ,,, for more easy operation maybe can install on dasboard ..🤔
Thanks for your comment 👍 very appreciated. Good luck with your project.
What size wire? I need a kill switch inside.
So is both wires from the kill switch running into the negative of the car battery? or is one running to the negative and one is running to the ground wire of the car?
Think of it like this, it's one wire with a brake in the middle to interrupt the feed. One wire, cut in half, with the kill switch connecting them back together.
Can you make it more clear? I don’t understand the 2 terminals
Great video!! I'm a single mom of three and have zero car experience and wouldn't even attempt this job even though this is what I need with my old car and electrical problems too costly to fix before I get a new one in a few months. So not meaning to sound ignorant, but can I just disconnect my battery manually every time I am done driving? I know it's more work but i have no other options. I just got a new battery and it still dies after a few days, so once I call roadside assistance and get it jumped again, would just taking off the negative bolt each day do the trick? Any other simple solutions or precautions for disconnecting and reconnecting the battery multiple times a day?? Thanks a lot!!
If your alternator is keeping your battery charged and the issue is drainage after the car is off, then yes.
Carlos Vazquez yes AutoZone tested my alternator when I bought the new battery two weeks ago. When I turn the car off the engine fan continues to run for hours sometimes.
The voltage/wattage on the battery is not enough to hurt you. Yes, you may have seen sparks when you touch the negative and the positive. But it won't kill you. Keep flammable things away, like gas or paper,it will ignite. If you just remove the negative you should be fine. Just make sure when you put it back it is very tight. You do not want the cables to be loose, then your battery will not charge.
One last note: your battery charges as you drive your vehicle. It takes a lot of power to start your car, and it takes a lot of driving to recharge that battery. So if you do a lot of stop and go driving and do not allow proper time(10-15min.of hwy driving) for the battery to recharge it will not have enough of a charge to start your vehicle. In cold weather batteries drain even faster when not in use. Hope this helps.
Carlos Vazquez thank you!!!
Although you want those fans to run after your vehicle is off, to cool off the engine. But after a few minutes they should cut off. Sound like a fan relay or temperature sensor may be keeping those fans on.
I have the same kill switch set up , will it remove a check engine light ?? Wondering because I bought a car with the kill switch like that and I want to remove it but idk if it will cause the check engine to go on
No it will not fix a check engine light. What ever is making light come on ,will eventually make it come back on. You probably haven't seen it , since every time you pull the key to the kill switch; you are resetting the computer, Causing the ecm to restart the troubleshooting process that will eventually find what the issue is, causing the light to come on. If you run the vehicle long enough without pulling the kill switch, the light will come on, if there are issues. Depending on drive habits it could take anywhere from a couple hrs driving to a few days....
Most check engine light issue are caused because of emissions faults or other safety faults. The kill switch will not prevent nor cuase a check engine light to come on.

The only thing am wondering if a vehicle with all this ECU system, if we disconnect for a few days than reconnect will we have to reset or reprogram some electronic system?
I wouldn't think so. For ex.,if battery dies nothing has to be reset... My problem was a shortage,somewhere, making one of the systems work 24/7 and thus draining the battery down.
@@carlosthemasteroftrades5070 am having a BMW X5 E53, something sure run 24/7. Left it for 3 days and the battery dies out.

Hey man, I love this beast, what ever it takes to keep it out of the junk yard...lol
@@carlosthemasteroftrades5070 on rainning day, ur electrical system will b fried!
@@antrinh5525 Actually if you listen to the video, u will hear that I put silicone seal , to keep water out. And if you know anything about electrical systems: there is such a thing as fail safe, they are called fuses!
My absolute last plan would be to drill the hood. I mean why? That chinese rubber cover will dry rot and fall off or get packed under snow. Gravity takes that moisture...down. thing will corrode in no time.
What gauge wire did you use to wire swich?
I think it was 10 or 12 gauge, reason being this vehicle battery is huge compared to most other SUVs. Best would be about 14g it more workable.
Im having the same problem on my 76 k10 thanks.
Which kill switch to you recommend? I don't want a cheap piece of crap I want a good one.
My celica is 23 years old. No electical issues
What gage wires did you use
I used either 6GW or 8GW stranded. Because that's what size comes off the original ground terminal in this vehicle. But it all depends on how complicated your electrical system is; I would go with the same or bigger from what the original wire is presently.
Carlos Vazquez thanks a lot I appreciate your reply!
So one wire on the kill switch goes to the negative terminal on the battery and the other wire on the kill switch goes to the existing negative battery wire?
Correct, it really is that simple.
@@carlosthemasteroftrades5070 Thank you for the reply man, I appreciate it!!
I tried it on my Japanese made daihatsu sirion and the switch burned out after a day. I used 8 gauge wires after a while the car won't start and then it started smoking. Now the switch is no good. So am left wondering what the hell did I do wrong? I installed the switch on the dashboard and fished the wires through the firewall. Please advise!
I hooked mine up just the way you did but the switch gets real hot any idea if that's normal or if not why it would happen?
If it's getting hot , you are arching somewhere ,meaning you have a loose connection somewhere or you have a faulty switch. It Should not get hot at all.
So basically just put new terminal splice.then run another wire to the original terminal?or how does that work bro
Pretty much what you said.
Remove terminal from battery, add cable from that removed terminal and run to the 1st terminal of the kill switch. From the 2nd terminal of the kill switch, run cable back to the battery and put on battery where you removed the 1st cable. Now you have a switch to turn on and off.
Ok gotcha thanks
Is it not worth looking for the parasitic draw?
Not on on an older vehicle like this one. It would cost more than the vehicle is worth...
Ez access just in case of an electrical fire to kill the battery
I was looking for someone to ask if it’s safe to leave my kill switch overnight cause I thought it used battery life but it’s actually a good idea right?
Leaving the kill switch on is like leaving a flash light on.... eventually your batteries will die. The whole point of the kill switch is to KILL the power to your battery, so it does not drain....unless you put a kill switch, for other reasons.....
@@carlosthemasteroftrades5070 I have it for theft prevention so my car doesn’t get stolen when I’m out so I should probably turn it off when I’m home huh
@@jorges3824 Good idea. the other way is make kill switch tru fuel pump relay. Put them together so if you leaved your car in a long time nothing to worry stole it. Thief's cant start the car and no worries about battery drain. two kill switch yeah
Does t make sense to me that the neg. Goes from battery to switch to old neg. Terminal that’s dead ended…..am I wrong
IF you have an overnight battery drain you need to figure out WHERE that's coming from. Disconnect is only covering up an underlying issue its not resolving it.
You obviously didn't listen..... but thanks for the comment.Share , Like and subscribe for more .
Did this actually stop the problem? I have the same problem and was considering this solution
Yes, I don't have a problem with the battery draining anymore. I can leave the vehicle off for weeks and jump right back in it and it will crank back up.
put the kill switch in the front window👌👍
My 2013 peter built lights cut out I shook the harness next to it lights came on next stop same thing checked batteries alternator fuses all good think it's my kill switch
My 1988 Chevy Van Can Sit 6 Months and Start Right Up
Wow, really? Through your hood?
I believe the switch would do better on positive/red wire side. I ran mine through firewall and mounted in dash under steering wheel.
That's great for you, I bet you have a Toyota!
It should be earthed out, ie disrupt the power flow on the negative side.
Go video for cars
Any battery draining issues after kill switch install??
None at all.
It's a parasitic draw. Use a multi meter to bridge the battery to the terminal pull one fuse Ata time until you see the voltage being drawn drop to 50 milliamps
Is there a reason why you didnt run the wire inside?
Yes, check rest of comments... fire wall too thick and congested. Wires too thick to try and bring into cabin.
@@carlosthemasteroftrades5070 ok cause i have a problem with my jeep where if i want my anti theft to go away and my dash and ac work i need to unhook the battery to reset everything and im thinking of puttin a kill switch now my question is
@@carlosthemasteroftrades5070 if i was to use a higher gauge wire say maybe a 10 or 12 will it be bendable enough to go inside?
I used a thick wire because my battery is very large. But for a jeep you should not need such thick wire and may be able to pass it through the firewall easier.
Just make sure it's not too thin and then you have a chance of it getting hot and maybe even melting or shorting out on you.
@@carlosthemasteroftrades5070 ok thanks for the advice
You sound just like Theo Vaughn
