Thankyou for helping me been messing with my 90 fox that has been converted to carb bored60 then stroked but never has run right since I was thinking it was msd box not wired correct and you confirmed that.its been a little over a yr I've been doing g this fox now I think I will be driving her soon thanks to you and your very helpful video and response
I have an aftermarket distributor, I don't want the magnetic wire just dangling there I'd rather use that instead of cutting and splicing, so my question is can I connect that instead of using the white wire? Btw I'm switching over to carb so hence the reason using the magnetic wire lol
I just bought a 90 fox, won't start after going around the block. I did a tune up ,plugs, wires, oil change, fuel pump. Same result. I bought a tfi relocation kit, same problem. I fixed the 3 compasitors in the ecm, 2 was bad. Same problem. When I bought the car it has a new distributor. So my next step is to hook a MSD 6 Al. Hopefully that will fix it. Your video is helpful with the wiring.
Needs spark, fuel pressure and air to run.... have you verified it has spark with a tester? Checked fuel pressure at the schrader valve on the fuel rail? There are electronics inside the distributor also that can cause problems... I prefer replacing the entire dizzy....
@@BMF_Garage yeah 40 psi and spark. Once it cools down it will run. It has to be something that gets hot electrical under the hood I'm thinking. I might buy a new distributor and coil also
Dizzy has a pickup in it that can cause that. I’d get a new one with all the electronics. Rock auto has them for around 60$ with everything... then you’re not taking a distributor apart trying to replace parts.
Hey man, thanks for the informative and clear diagrams. I am trying to wire up my stock tach in my ‘83 coupe to work again, I don’t like the look of an aftermarket tach. However I don’t have the TFI style ignition, my car has a magnetic pickup style distributor, with violet and green wire that goes into the MSF box violet and green wire( the plug not used in this video) Would I be able to use one of those as the signal wire for the tach? Also, do you know which one of the three spots on the back of the tach circuit is the signal input? I’m guessing one is ground, power, and then signal. Thanks, let me know if you have any suggestions. I may just have to buy a tach adaptor for the MSD box.
Of the violet and green wires, one should be positive and the other should be negative. You should be able to take the negative wire to the factory tach for a signal however the pulse count might be different than stock so if it’s off, that would be why. As far as what terminal to connect it to, I’m not certain on that without looking at it too much. Will check my manual and see if it specifies a wire color or termination point.
Excellent explanation. But i am surprised that it runs reliable with the choice and condition of the wiring connections you have used. I definitely wouldn't be soon lucky lol
Love your videos, when i found your channel it was like binge watching netflix. But its been a minute since you’ve posted one, mainly cause youve already covered so much ground! My comment or actually question is what about wiring a monster tach? Do you still need the 6al tach adapter or is there another way?
87 mustang 331 carb set up was a 4 cylinder. Have v8 cluster and can't get stock tach to work. Car had a aftermarket tach in it. Can I just run wire from aftermarket tach that's at dash to wire that goes stock tach or do I need an adapter. Msd box , distributor and coil set up.
it depends on where the wire to the aftermarket tach comes from. What typically happens in a factory vehicle is the tach is ready from the same negative wire that goes to the coil. With a msd box, your tach should still be connected to the same wire that is triggering the msd box, usually a yellowish wire if I remember right.... But you need to connect the factory tach to the factory trigger wire for the coil. it pulses the negative signal from the distributor to fire the coil and also is a signal for factory tach.
So I have the exact box as you along side of msd blaster 2 and and msd distributor that plugs into the connection you tucked away. And that’s my setup so do I just tuck the white and the red away since I don’t have tfi? I am carbed btw. And this setup should provide spark correct ?
Not sure what you mean by wire them all together… like literally connect them all together? Cause that won’t work.. you have to follow the wiring diagram. The msd gets wired in between the factory wiring…
When you cut the wires on the tfi do you just use the wires going in the distributor or do you need to use the ones that you've cut on the right too? Same with the harness going into the firewall that goes to the coil once you cut them wires do you just use the harness and not the wires going into the firewall?
You need both sides. Look at your factory coil wires. There’s two wires. You’ll cut the two wires going to the coil in a spot that makes it easy for you to wire it in. After cutting those, The two wires coming from the distributor are the input to the msd and the two wires going to the coil are the output from the msd. I don’t know off hand the colors on the msd but that’s on the wiring diagram. Then you connect the think red and black on the msd to power.
Shouldn’t need to connect that on the foxbody. The tach output is typically just used for a dyno situation or tach that needs it. Factory tach and aftermarket tach that in use just connects to the factory trigger wire and doesn’t use the tach output from the msd.
@@BMF_Garage my auto meter tach has a green wire that is tapped into the negative that goes to the coil… should that grey wire go to the green from the tach ?
I don’t think so. Pretty sure the auto meter tach should connect just how you have it… that’s how mine is… then you should have a selector switch on it for 4cl, v6 or v8..:
So this works without the efi ecu? The MSD controls advance? How is advance tuned? I have a 351w from a 95 F250 I am swapping into a Falcon with a carb. Thanks
Still wires up between the coil and dizzy. Power wires on the msd box go to the battery. Input to the msd box comes from the dizzy and the output goes to the coil. The msd is just taking the factory coil signal from the dizzy and amplifying it then sending it to the coil. Factor coil wires connect to the input on the box, then the box connects to the coil.
Clevor BMF thanks. Been trying to smooth out my idle on a Jeep cj5 304 with duraspark. Replacing small cap with adapter and large ford cap. Don’t have a mad box yet. Going to see if the distributor mod helps first.
@@BMF_Garage ok. Trying to eliminate that tfi! How about getting a points dizzy then doing a Pertronix conversion? That would give me the weights for advance and Hall effect for coil grounding. Would this mess with the computer?
My apologies, just been busy with work. It depends what you’re trying to do. Are you just curious about the rev limit or trying to do the rev limit with the msd?
@@BMF_Garage I am wondering what to do with the rev limiter. I have a 1996 F150 I just built a 95 bronco engine for it The engine is the same as factory original. I didn’t do any serious mods to the new engine it’s basically stock. I am running it with the factory 5 speed transmission the truck is 4x4. I did not activate the rev limiter on the MSD 6. I guess I need to set up the rev limiter? I wonder what rpm I should set the rev limiter at. What does the rev limiter do?? I really appreciate you answering my questions!!! Thank you!!!!
Rev limiter is good to use. The msd will pull spark to prevent the engine from revving higher than what you set it at. If you didn’t have a rev limiter, the engine could rev too high and damage itself. I’d set it at 6000 for a factory engine. That’s a good safe limit in a stock configuration. You don’t have to connect any extra wires to/from the msd for the rev limit to work. You just have to set the msd at the desired rpm (6000). Hope that helps!
@@BMF_Garage that’s exactly what I I needed to hear. I’m trying to watch the video on you with 1320 video but it won’t download which is really weird. I really like 1320. Video they do a really good job on showing what’s going on in the drag racing world. That’s way cool they hung out with you. This is the last thing I am doing to my truck. Now I’m going to finish my 92 camaro. Thank you very much for your videos and your time answering my questions. I wish the best of luck and success on your mustang. I love your car!!!!!
So what u have to cut into ur dizzy wires I have the 6al 6025 the newer 1 with out the pills I have a tfi msd dizzy to I just a little confused so u need to cut into ur tfi plug?
So you’ll need to cut the two wires that go to the coil. Then wire the red and white from the msd box to the side of the wires coming from the dizzy. Wire the orange and black from the msd box to the coil.
Clevor BMF OK I got it I just got confused I never hook 1 up before thanks this is my first 1 I have a 87 notch with a 89 harness so basically u run the wires into the coil wires then use the coil wires that u took out of coil!
I'm trying to visualize this on my 93 gt, would I cut and splice the red and tan wires to go to red and white INTO the msd box, then splice the orange and black coming out right to the coil in wires?
And let me just clarify lol, I cut the factory end off that plugs into the coil due to it being a different type of coil, it has a rubber end with black and orange wires coming out, I just didnt know if I run the wires from the msd box to the pig tail? Man I wish someone good with wiring lived close to me in NY
Na you got this. It’s easy! Just think or the msd box as going in between. If the cut the wires going to the coil, the side of the wires not connected to the coil is your input to the msd box. The side of the wires connected to the coil is your output from the msd box. All the msd box is doing is taking the signal from the car and amplifying it then giving it back to the coil.
@@BMF_Garage it was my thought exactly. So those two wires that I cut off the factory coil and run those to the msd , then run the wires out of the msd to the after market coil and be done?
With that I can eliminate the computer on my 1986 multi injection thunder bird and install like a sniper efi I don't need the computer from my car or nothing that comes with it. Tell me what do I need to make my car run money no problem. Because I want to install my sniper efi that I bought.
Megasquirt is plug and play with the factory harness just take out factory ecu and put in the megasquirt 🤷🏼♂️ sniper works too but I believe there’s some wiring to do if you didn’t buy the plug and play kit
So fucking frustrated. Your hand is in the way and the camera is shaking when you're explaining which wires go where. So do all 4 wires go into the same place? Your literally saying red and white go in the the plug, and the orange mad whatever go into the same spot. I don't get this man.
Sorry bro, I’m tryin over here 🤷 Red/white go to the factory coil wires red-lt green / yellow-white in that order. The msd orange / black go to the coil positive / negative in that order.
It’s taking the factory coil signal and amplifying it and increasing the amount of sparks per trigger, hence msd = multiple spark discharge. It just goes in between the two and modifies the signal
What if I've converted to carb do I still run msd the same way
Yup, same way.

Tach Signal Wiring Explained (With or Without an MSD Box)
ruclips.net/video/gzPHMcc2fHE/видео.html
The tach video was great...the simplified diagram near the end really lets it hit home for us dummies, great job as always!
Thanks man!
so I don't touch anything with the microsquirt, I just hook it up regular like if I were to have the stock ecu.
Yes sir, that’s correct.
The ecu stills controls the spark by giving a signal to the msd box. The msd box just makes the spark hotter
Is the connection from wire to wire a splice or what, im not big on electrical components and can't figure this thing out
I used a butt splice with a mechanical crimp connection. You can also solder and heat shrink if you prefer.
87 mustang 331 carb set up was a 4 cylinder. Have v8 cluster and can't get stock tach to work. Car had a aftermarket tach in it. Can I just run wire from aftermarket tach that's at dash to wire that goes stock tach or do I need an adapter. Msd box , distributor and coil set up.

This box can’t control advance, just spark. There are some msd boxes out there that can control timing though...
Anyone done this with a holley efi terminator X?
What if you wanna use a non tfi dizzy but keep the harness im lost lol?
Those are usually easier as the msd can be wired directly to the coil. Msd has a ton of helpful wiring diagrams online
What about using the old DuraSpark Distributor? How do I wire it up? Thanks
Still wires up between the coil and dizzy. Power wires on the msd box go to the battery. Input to the msd box comes from the dizzy and the output goes to the coil. The msd is just taking the factory coil signal from the dizzy and amplifying it then sending it to the coil.

1989 bronco, 5.8. If I use the MSD module does that totally eliminate the tfi module on the distributor?
No it doesn’t. The msd simply takes a signal from the tfi and then gives the amplified multiple spark signal to the plugs
@@BMF_Garage ok. Trying to eliminate that tfi! How about getting a points dizzy then doing a Pertronix conversion? That would give me the weights for advance and Hall effect for coil grounding. Would this mess with the computer?
Argh! TFI triggers injectors, forgot that! Is there a work around for injectors? Hmmmm
You could just do an msd distributor with an msd box to eliminate the tfi
