8G 3rd Generation Tail Lights Wiring Diagram

[galantebeige]

SUMMARY UPDATE FOR THIS THREAD: The Wiring Diagram below is correct. It is the basic design to wire and solder your 3rd Gen JDMs to the US plugs. Be sure to read the whole thread for details and historical info.


+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_ Historical starts here:

So I read a few posts and got really confused, since they don't agree.

I got my tail lights and need to get the wiring done. I drew this diagram, and I would like to get some feedback if it does look right, or if I got it wrong somewhere. Hopefully, it will also help others later on.

What I find most confusing is that at the end of both the JDM and the USDM harnesses (before the end plug) they are just the same, 4 different wires and the black wire.

So, one green, one green/white, one red/blue, one green/blue and one black.

I would think then that connecting them together is just a simple one to one (same to same) soldering job. (And not a more complicated thing as I read that a few greens need to be put together into a single one green....and so on) Am I missing something?

BTY: Pictures and info here from other posts from the TGC forums.

wow bro good job! sorry i cant help, but if this is right, i will go off this.

[Danger DANJ]

I did a little writeup years ago and for me there are 7 wires on my JDM harness. The same 5 wires (same colors) that you have plus another green wire and another green/white wire. So, I had 2 green wires and 2 green/white wires. I just twisted the 2 green wires together and did the same for the 2 green/white wires, then soldered them to the matching colors of the USDM plug.

The JDM harnesses must have been changed at some point to combine the 2 green wires and 2 green/white wires before they get to the plug.

So, just connect the matching colors and you are good to go.

Okay, that's great!, I go with that and do it that way. Soldering each matching colors to each other.

much needed tutorial, i'm still running the stock wire setup on my 3rd Gen tails.
Thanks much galantbeige! :thumb:

I got this from RedGalant2k1:

Here is a break down of the wire colors:

Green/White = Running lights. (When headlights on, both top lights on your 2nd gen JDM taillights should be on).

Green/Blue = Turn Signal

Solid Green = Brake lights (when pushing pedal down) When wired properly these should also both light up when braking.

Red/Blue = Reverse light.

Black = Ground

I updated the diagram a bit more. The only important change is that solid green is brakes and green/white is running lights.

The diagram itself is correct. This detailed info is only needed for those of you who want your light bulbs to do something different, just mix and match your cables.

[galantebeige]

Finally got these tail lights up and running, had unrelated (maybe) issues, I blew a fuse....and was going crazy.

Okay, to follow up on this and give a conclusion. It is just as the diagram says. It works great!!

The diagram will light up the bulbs as originally intended. So, use with confidence, it is the right info.

By the way, a BIG THUMBS UP to our Japanese seller Triggermauve!,

one correction to your diagram

all the bulbs are 1 filament except for the outside light which serves running/brake light

the difference between the jdm 2nd gen and 3rd gen is that on the 2nd gen both light serve as running/brake lights while on the 3rd gen only the outside light is running/brake light

good job on the diagram though, i got lucky with my tails and i got harnesses with them with the plug so all i have to do is cut the plug from the car side and connect the jdm plug there which was matching wires

I have had my 3rd gens for awhile but would like to rewire mine like Kalimidad had his with the inner bulb being the brake light.

[galantebeige]

Nice pics!,

I see those colors from the JDM cables look slightly different from mine. Your red/blue looks like red/green?

Anyways, I think what is important is to follow the cables from the bulb itself, noting it's location and purpose (and colors) , and splice them into the USDM harness corresponding cable....

About the bulbs, I will have to take the tail light out, and maybe I will do that soon to double check.

Thanks for the clarification, what we want here for everybody is the most accurate info possible.

The inner ones are brakes. That's what I just said in my post

just follow this guide and you are good to go

[blue8g]

what's the easiest way to wire these since the tailights and the car have a female adapter...

[galantebeige]

Once you know which wires go to which bulbs, on the JDM side, and know what color wires makes certain things happen on the USDM side, you can wire them to do whatever you want.

For example, if you want the turn signal to be the brake....
find the green/blue on the JDM side and splice together with the solid green on the USDM side.

It's all in the diagram above now. The color codes are what the USDM colors do. (And what the JDMs do as well).


BLUE8G:

You need to cut them and solder them together as described in the diagram. The cutting points are just at the end, before the JDM plug, and some inches of wire before the USDM plug (to be able to solder some of this length together).

[galantebeige]

Here's a good picture from the thread
https://www.thegalantcenter.org/showthread.php?t=17510,
to explain what the soldering will look like (at least it is very close). I believe it is DangerDanj, who has posted here also. His helpful comments are above. Basically, if you get a 3rd Generation JDM set, it may might not be exactly the same as others have. But the principles are the same. Same color cables, maybe more or less of them, etc.

[blue8g]

the diagram worked great but the moron that wired the car from the factory had one color going into the harness and it was switched with another color wire coming out so we had it backwards for a while, then once we fixed it, i popped a chub for the beauty of it all

[galantebeige]

I' glad you got it done, Blue8G.
I can't believe the factory messed up!

[blue8g]

i know, then again people from illinois are a lil bit messed up...jk but seriously

[galantebeige]

maybe that's why people say "cars built in america are ......"
jk

I am posting a few pics of my JDMS...and how they look when wired following the diagram.

[blue8g]

ooh mine's right!!!!!!

[Rodriguez]

Is this the same for the vrm taillights?

[AVERAGE]

My running lights are right, but i believe i used a tut off of Prophet's site. My inners arent brake lights.

[02redgalant]

Is this the same for the vrm taillights?

if your talking about 2nd gen lights

the wiring is most likely the same
but the running lights stay on for both bulbs and both light up for brakes

[Joker96]

i bought the car with these tails on it but my reverse lights are not working all others work, could this b bad wiring?

[wetamup2k3g]

More than likely, I can't see both reverse bulbs being blown, but it's possible. Check your wiring, you may have other issues besides the taillight wiring.

[Skyforger]

if your talking about 2nd gen lights

the wiring is most likely the same
but the running lights stay on for both bulbs and both light up for brakes

So basically the wiring for 3rd gens is the same as 2nd gens? Looking for a set of 2nd gens, but keeping this diagram handy.

[Galantman03]

^pretty much, but if you don't know where to start on the 2nd gen, look at the bulbs, those will tell you what they do, aka 2 filiment, brake and running lights, one filiment brake or running lights.

[lucap100is]

@skyforger: pm trigg, he can get you a set.

[Joker96]

i checked my bulbs they are good, tried checking to see if i got current going with a multimeter but none is going to the reverse. mine are like pluug and play i dont see any soldering or cable works on the plug.i just see a plug connected to another plug just as if it was stock. iil take a pic later

[Galantman03]

take the reverse lights out, with power off, meter on the ohms setting, its the omega symbol on the meter. if you get O.L., they aren't even connected, if you have an extremely low reading, like 50 to 125 ohms, something low like that, then you have a short, and you need to find where. I would first check where they are soldered together.
