Hi
I got an android system for my 2015 Lexus GX460, but the wires and harnesses does not match. Can you help me with it?
Hii I have Mazda 3 2018 I need one harness kit for line out converter can you tell me where to get one ?
to connect a KEY200.4 Smart 4-Ch amplifier. Amplifier (auto-EQ/processor) in a 2020 Ford ranger with the original 8-inch stereo, what do I need? What harness works? Also connecting a bass amplifier? thank you
Send me a message on facebook or instagram and in can walk you through it.@@davidgleza356
I had been trying to find a video like this for weeks, and then today your video popped up in my recommended. Glad I was able to find it, this helped me a ton!
So many people complain that butt connectors and scotch locks are a poor way to join the wire's, but I am here to tell you that I've not had one problem using these two methods. Using the correct tool for crimping is the trick to doing a professional job. Stop buying cheap tools is another reason why some wire connections fail. I had an Alpine head unit for 15years in a truck using scoth-locs, not a single problem with wiring connections. Yes you can solder the wire's but just takes longer to do the job.
There's no tool for scotch locks,they are a terrible connection
They are decent but don’t hold up forever
@jkink8049 no they aren't
@@470ruger There definitely are pliers made for scotch lock style connections
One thing that we do in the aviation maintenance industry is stagger the locations of butt crimp connections, so that they are not next to each other in the wire harness.
Putting them all next to each other results in over-wide lumps in your harness, which can cause problems.
That is smart, I will do that in my project!
I do this to spliced connections, I just thought common sense, not an engineer here. I guess I have some design background by being curious but my strength is in Quality.
@@scientist100you'd be surprised how thoughtless some people are
Thank you for making this video, as I am using this as my template to install my new radio.
Great info!!! Your videos has helped me so much with installing stereos into my 1998 Jeep Cherokee, (I’ve replaced like 5 stereos in that car😂), and in my 2004 Tahoe, which I no longer have.
Now I’m getting ready to install a Jvc double din stereo (KW-X840BTS) into my 2008 Nissan Sentra!!
I’m trying to wire one for the first time in my 2004 Jeep grand Cherokee and can’t seem to figure it out
@@elijahgreen5121 have you cut the factory harness?
Great content very simple and straightforward thanks
Glad it was helpful!
Great video! Now i feel more confident in wiring up my Soundstream VR7HB radio head to my Chevy Captiva. Im sure ill have more questions later on!!!
This is another awesome video. Thanks for sharing
Awesome tutorial video 🎉🎉🎉
Very very useful video thank you sir.
Thank you for your videos!!! Now I feel a little more confident in what I'm about to do with my wife's car. lol
Great video . Thank you
Amazing video thanks very much
This is really helpful thanks
Mr. Beast, today is possibly the greatest day of my life. Why, you ask? Because for the first time ever I am the first to comment on one of your glorious videos. I hope each subsequent commenter on this video will come to know the goodness of Provo Beast that I have.
Thanks again :)
Thank you so much!!
First of all I want to say thank you for showing how to do that. I wish you would have shown the whole thing one by one. Anyways I don't understand why people don't like to solder the wires together where I live they told me nobody does that. I wish you lived in my town. I wish you would do another one I bought a Kenwood aftermarket stereo for my truck and I'm trying to figure out how to do the wiring harness bra not to cut no wires seems pretty difficult but watching your video looks pretty easy but I'm scared. LOL. I wish you would do another one but do any choir where we can see how you do it. Thank you very much.
I wish you'd shut up.
thank you
Will do.

Thanks for all the great videos. I am about to start on a radio upgrade on my 2001 Ford Excursion XLT and have watched your related videos. However, the recommended Metra 70-1771 harness has only a single 16 pin plug. The 2001 excursion has a second plug and wiring harness which plugs into a port on the back of the factory radio identified as an amp but actually runs to the back of a center console rear speaker controller. I believe if this is not connected, the rear 4 speakers will not function. Please advise as to a solution and/or can you identify the correct Metra harness. I have looked at their website but they identify only the 70-1771 part number.
Hi! 🤔 Did you find an answer? I'm running into the same situation with my 2006 Explorer. Thanks
Can I ask a question about the
yellow and red cables if the red is not connected to the ignition
and there both onto a live
Would this make the battery 🪫 go flat if the vehicle is not used for like a month
Thanks for the video by the way 👍
Hi i Recently fitted some premium speakers into my car, and I have an android head unit that I ordered from eBay the sounds were playing just fine with the headunit untill it stopped working n the fuse blew and smoke started coming from the head unit i went back on ebay n have seen that the wiring harness is not compatible with Premium, aftermarket speakers what shall i do ???can i get a harness that is compatible??
On the amp wire, why is it joined to the factory harness instead of hanging loose. Isn’t the power coming out of the Head unit? If so where would it be going to in the factory harness? An antenna maybe? Thanks enjoyed it much.
Good day. Thank you for the video. Do you have one on connection/installing aftermarket amp and stereo. I’m still a bit confused. Do I need to make a t-connection with the factory wiring and the radio harness or do I seal off the speaker coming from the harness and go from stereo/RCA/amp/factory wiring?
i just installed a pumpkin 10.0 D Din my chevy colorado. Have you ever hard of a pink wire called back car? The stereo only came with user manual, and just a diagram on the stereo. I was wondering what that wire was for? I thought it might be for reverse but its not. I had few wires left over like SWC Brake and power att. The harness I had vss speed dimmer power att illumination and. I need to fix illumination. I have no lights on the buttons. I cant see them at night. I hooked up a orange wire in the harness call dash light. So i got to fix that still. Let me know if you have and info that could help me out. Thanks!
Any advice changing mci bus wiring
Awesome
Thank you much for the videos. Its detailed and through..loved all the hard work you've done.

I’m trying to install an aftermarket radio in my 2009 dodge caliber. The harness isn’t fitting but I have another aftermarket harness that’s does but doesn’t have all the features the the other harness has. Is it possible to wire that harness that does fit with the extra features?
How do I wire up speakers to an amp with an after market radio? I have a aftermarket radio and amp but confused on speaker connection if it goes to. The radio or car harness
after i install my pioneer avh-1550 nex the sound of the dash lights does not sound like when i put the signals i cannot hear them. They will have a suggestion or something that installs wrong. thanks for your help
Do you still need to use the black wire to ground it? if you’re already using a premade harness connection? That came with the radio? There’s a a black wire in the harness and then there’s a second black wire loose..?
Hi I would like to know does it hurt anything if you decide not to connect wires that match
Do you connect multiple wires together like 3/4 yellow
Which one would be good for a Pontiac g6
The blue wire for the Harmony HA-706502 harness states that it is for a power antenna can that go to the blue white wire on a pioneer DEH X6710BT stereo for the remote control?
I am doing something similar myself but instead of changing the plug onto the back of the radio i will be making an adapter from the original wiring harness plug to the cars later counterpart wiring harness plug ( gives who ever owns the car more radio fitting options)
For wires that size you used 4mm tubes or 3mm?
Hi, how can I connect the steering wheel controls on my 2010 Ford scape?
Do I need a Meastro data link harness system for my 2007 Ram with a double DIN unit (Kenwood) if the Ram doesn't have steering wheels radio controls, doesn't have climate controls run from the head unit. It has separate knobs or no tire pressure TSPM on wheels? Or will just a harness adaptor be fine ? Even if it has Android Auto i believe that works from the phone app.
Are their harness adapters for a vehicle with two plugs?
Quit Question Im trying to find the right audio harness for my 2020 f150 xlt

What wires do we need
I cant get power to my cars factory amplifier.. I know its blue/white but no matter where I connect it I get no sound... the unit works,it gets power and seems to be working .. but no sound then amp fault comes up on the display screen.. what else can I try
What if the cars harness doesn't have a solid red cable to connect to the radio's harness?
I need help tho i need an adapter for a honda accord 1998 cg9 stock subwoofer/amplifier to aftermarket radio. Cant seem to find. If anyone know please help
Where can I get a harness for my 04 gmc envoy that has, Onstar, Bose,(for now), chimes, and steering wheel controls. Sonic has several, but none of them do everything you need. Always 1 or 2 things missing so you have to buy extra harnesses to get everything to work. Can't believe this can be so messed up.. R
I just paid $14.79 instead of making one from scratch, second in (gray on darker gray)
Time is money, and I've got better things to do with mine.
I'll update soon as I receive it.
I think I did it mostly right with my car (2007 Pontiac Vibe). There are some wires though that are questionable: blue to blue/white, orange to orange/white, and purple to pink purple/white. I am questionable about those wires. Will it do anything funky to the radio since they weren't exactly alike? Other than that, I am pretty sure I did it right the best I can. If not, then I will just need to get a different kind of stereo wire for my vehicle.
Match function to function, don’t just rely on the color alone. Depends on the radio harness and radio manufacture you are using to know what goes where.
Hoping to get a response soon..
Please read thoroughly 🙏🏼 👍🏼
Hi appreciate your video alot it's very helpful. Help!! 2004 camry harness(jbl)
So I bought a harness to connect/bridge to the vehicle harness and stereo harness.
Bridge harness has 6 brown wires I don't know where they go. No instructions were with the bridge harness.

(Orange)(x6-brown wires)
Then..
On the stereo harness, these wires ended up not getting connected: :
(pink&pink/black)(x2-orange/black)
(x2-blackground)(brown-labled)

What is the gauge of the wire for these wiring harness? So that if I decide to crimp I will know what size to get.
18 Gauge
Ok I am really hoping that you can help me out with something. The adaptor that I am using has a blue/white wire which is labeled REM OUT. The radio harness has a blue wire. I saw that you connected the blue/white wire to the blue wire but they both run to the micro bypass. If I don’t need a micro bypass do I simply wire the two together or do I cap them off and not use either of them?
The blue and white is your amplifier if you have one... If not you can ignore it if you have one it'll need a 12 v connection, I'm working on the same issue just sharing what I've learned so far
Yes blue white to blue white as it will trigger your factory amp to operate when the radio is on. Without it, you might not get any sound. We also used that blue white for the microbypass (for pioneer and alpines).
Do you have to keep a separate earth wire out and ground it? Or is it included within the harness?
All depends on the harness and year, make, and model vehicle. Most harnesses include the ground in the harness already. Some older vehicles like nissans require it.
If you're not comfortable or use to soldering check solder seal wire connectors way better than butts or crimp caps and about 5 bucks for a set of 100.
I didn’t even know those existed! You rock! Just saved me a bunch of time!! 🙌🏻
I've iasue with my chinese android unit. Every few months I have to open the dashboard and replace the harness adaptor due to noise in the speakers coming from loose connection while I can't see any when I check visually.
I've factory amp and using canbus. Any advice.
GO with a better brand radio, unfortunately. Those cheap Chinese units are terrible.
I was just struggling, discovered that one of these companies had given me a backwards diagram. "Oh cool easy fix" I thought....
Until I then found out that the ONE wire needed for steering wheel controls did NOT have a pin or wire inside the harness.....
I have a 2019 cascadia big rig.. l need my steering wheel controls to function.. can u help?

In my radio doesn't work the steering wheel control. My radio is 7010B model and car is Hyundai i30 2009, Could I get ant information please. I will be really appreciated. Thanks
You need to purchase a control unit for retaining steering wheel function
Question: when using a harness adapter all that is needed is to connect the correct colors with the adapter that came with the radio/cd player right, what would be the reason to bypass the adapter harness, and go directly to main harness.???????
I’m not sure way you would consider cutting into the factory harness when so many adapters are available. I would NEVER recommend not using an adapter.
@@ProvoBeastAudio I ask because a friend of mine bypassed a few wires on the harness adapter, my mouth dropped open,because I assumed all he had to do was connect the correct colors(with the adapter and the harness that came with the radio), but so far the radio/cd player works fine, I'm just shocked that he bypassed the adapter harness....
Have you ever heard of a "communication wire", a wire that if its cut the car won't start.???
@@samuelhepburn2636 Many communication wires, often known as canbus or data wires which is why smart harnesses are needed.
@@ProvoBeastAudio but in your opinion does a 2005 Saturn ion 4 cylinder, needs a smart harness(thanks ).????????
My stock stereo had 3 plugs. One for the antenna, one that plugged into my connecter, and a smaller one that I don't know what to do with. Please help
probably on star or xm
Third plug might be either Sirius, Factory amp, or probably onstar if you’re vehicle is a GM product (chevy, gmc, buick, etc)
Aap kay number hai AlPINE amplifier socket ahi kya
When connecting the wires can you use electrical tape?
You can but it's not recommended as the adhesive can eventually dry out and the wires will become loose.
I need one for an 82 amc eagle hahaha
Hey I have a question. My friend let me have 2 different head units but they don’t have their wiring harnesses. Does that mean they are useless like that or can I buy just the harness itself? One is a pioneer and the other is JVC and they are both single din
You can get them through eBay, last year, I bought a harness for a pioneer mvh-21bt that I’ve gotten for free that was missing it’s harness and it worked great without a problem. What are the model numbers to the Jvc and pioneer radios? I can probably find the harnesses for each unit and can link them here
You can also get Bluetooth microphones for each of them too if they’re missing & need them as well on eBay
@@ernie0699 ah I figured it out, both of them were junk but I was able to return the harnesses to Amazon
@@princealideababwa1485 no problem, most non original harnesses are junk, so finding original brand harness is difficult to find, but you’ll be lucky if you even find original plugs on eBay or Amazon. The harness to the Pioneer MVH-21BT I had wasn’t Pioneer original, it was a knock off brand & it worked perfectly good for me. If you’re still in search of the harness’s for the Jvc or pioneer, I would recommend reaching out to each company and see if they have one harness in stock, im sure they’ll do. Hope this helps!
@@ernie0699 you know, surprisingly enough both the head units themselves were junk. Sorry that’s what I meant but I ended up getting a $20 Dual brand Walmart head unit and that thing sounds really good. It’s has Bluetooth and all that and I was able to hook my subwoofer up to it and it sounds great. Pretty good deal honestly

After successfully connecting all of my wires, harness to harness. Radio always stays on after key is off? How do I fix this?
Tons of variables here, depends on the radio, depends on the install parts, depends on the vehicle year, make, and model! I can help you more specifically if you reach out directly to us on facebook.
I want to hey one
You kind of sound like David Wallace from The Office
My harness that comes with the radio his missing what do I do?
Look for one on eBay.
I connected mine but it keeps popping the radio fuse what am I doing wrong?
You have a short somewhere. Time to recheck all wiring.
what if colors don't match
They should. Which colors don't match? Sometimes colors are not exact, so match what wires are labeled on the harness and what the radio identifies them to be.
Like i have pink color in my harness..doesn't match
Where did he find the most Financial success basketball or Media?
There’s extra wires
no purple wires now what
we got it all 4 speakers
so stupid question I buy one connection part and the other comes with a headunit?
You got it.
The wiring kit you buy is to connect the wires of new head unit to your factory connection! Factory plug>vehicle specific wiring kit>aftermarket head unit
@keegan Long If you mean avoid buying the $10 adaptor that makes it plug and play, then you would be hardwiring it into the car and can’t just remove the radio for service
Idk why I'm so intimidated to do this lol
I learned absolutely nothing watching this
Your loss.
