HELP! LED tail light resistors..

So, I have my eBay LED tail lights installed (I've had them since winter, actually), but the 'light out' warning on the dash is driving me insane. I bought some load equalizers (aka resistors), but I have no clue what to tap into on the other side (besides the ground).

DOES ANYONE KNOW? I've searched everywhere and haven't found anything..

Go to bed, Alec. LOL. j/k. Actually, I should be in bed!

Anyway, I'd check with Nick (JLevi), or he could point u in the right direction.

Are those the same tails that Tien installed, or are these new LED's?

Alec,
One side of the load resistor gets tapped into the ground and the other gets tapped into the positive wire of the light you have a warning for. If it's the parking light/brake light, you need to tap the positive wire of that and the ground.

Here are the wires for your taillights, tap into the colored positive wire of the light you have the warning out for and the ground wire (brown). I am not sure how the LED's are setup, but my guess is that you need to tap the positive for the combined brake and parking light (black with green stripe). You may also need a 2nd load resistor on each side tapped into the parking light only (gray with purple stripe) but try just the combined fist.

Pre-facelift SEDAN tail light wiring:
Drivers Side Wires
Pin 1 - White with a brown stripe - Ground for the interior trunk light
Pin 2 - Blue with a green stripe - Positive for turn signal
Pin 3 - Brown - ground for parking and brake lights
Pin 4 - Red with a yellow stripe - Positive for the interior trunk light
Pin 5 - Gray with a purple stripe - Positive for parking light only
Pin 6 - Black with a green stripe - Positive for the combined parking and brake light
(pin numbers could be reversed - I didn't check on the plug)
Picture of plug with wires


Passenger Side Wires
Pin 1 - White with a brown stripe - Ground for the interior trunk light
Pin 2 - Blue with a brown stripe - Positive for turn signal
Pin 3 - Brown - ground for parking and brake lights
Pin 4 - Red with a yellow stripe - Positive for the interior trunk light
Pin 5 - Gray with a yellow stripe - Positive for parking light only
Pin 6 - Black with a blue stripe - Positive for the combined parking and brake light
(pin numbers could be reversed - I didn't check on the plug)
Picture of plug with wires


Let me know if you have any other questions, I've messed with the wiring a lot. My LED's (DEPO facelifted style) also have bulb out warnings. I had to put load resistors on both the combined brake/parking light and the parking light wires. Good luck.

alright i put load resistors on the combined and just parking, but they didn't work. how many ohm's are they supposed to be?

They should be 6 Ohm, 50 Watt resistors. I got my load resistor kits from here - http://www.superbrightleds.com/tail-brake-turn.html

Scroll down the page to see them.

Ladies and gentlemen, the man above me knows what he's talking about !


Very useful stuff over here..

I have an 01. Build date 6/01.. No new LCM needed, no dealer reflash. And this was done on my Vert using oem led tails from Tischer !!

I used 4 resistors in total. I connected the brake and tail lights to one resistor and the ground.... And on another resistor, I connected the turn signal and the ground on the other end.

So you have to buy $20 worth of resitors and cut into your wiring harness as opposed to having the LCM flashed?

No cutting involved, just wire taps. No harm done.. It's cheaper than a reflash too.

They are, but my friend supplied me with the ones for a facelift and/or euro model. Pre-'01 LCM's are coded differently than mine...

Alec, do you have a pic of which wires you ended up tapping? Like you the indicators are driving me crazy.

I just tapped the combined wire (Black w/ Green Stripe) and it worked perfectly. It's different from car to car though, just make sure that you have the proper resistors and go ahead and experiment.
