Guys,

There are two harness going into the factory stereo on my 04 TL. A bigger gray one and a black and white one. Which one comes in from the stereo?

Thanks.

 

Your best bet is to pop the speakers with a "D" battery. Tape a wire to the positive tip and tape a wire to the base.

I am looking over a read out from directechs.com and it does not say the harness color just the wire colors.

First color is (+) positive and second is (-) negative. If the speaker pops, that is not the harness coming from the deck.

LF = lt. green - purple
RF = blue - red
LR = brown/white - red/yellow
RR = red/blue - yellow
Center = green/white - blue/yellow
Sub = yellow/black - lt. green/red

 

Thanks for that.. Yes, the wires coming from the HU are on the Black and white harness.

The Gray harness contains the wires going out to the speakers.
