Buick lesabre wiring diagram
 

I am putting a hu into a 02 lesabre. I wired everything up and the acc isn't getting hot. I know it works because the factory player works. There are three pins on the factory harness I did not use, scosche has these labeled "mute" and they are all brown. Could this be the reason that the acc line isn't hot because I didn't wire these mute lines? They are the bottom three pins on the right side when you are looking at the factory harness.

It appears that the buick doesn't have a 12v acc line, and I would need a $70 in order to make this work with the rest of the shit. Anyways, what can I tap the 12v acc line into on the buick that will make it work? I don't really want to run it straight to 12const.
I bought the cheap harness from scosche, not the "interface" GMRC-04.

I will tap into the RAP relay under the back seat I suppose.

Note to self: Do not ever work on a GM vehicle AGAIN, unless the owner wants to buy the "interface" for $100.

STOP.....RETURN THE CAR TO STOCK AND MAKE THE OWNER PURCHASE THE HARNESS

That car is part of the class 2 data bus protocol. There is one or 2 purple wires which are the data bus communication lines which route through the radio. If connection is severed depending on vehicle platform different circuits are effected:
-airbag
-abs
-warning chine
-ignition
-vss
-hvac
-illumination
-ecu

And its not a sudden thing. Problems can surface days or months after interruption.
Use the proper parts...its not worth the headache.

Shit! It's already done.
I'll the owner know to see what they want to do about it. Do you have any links to information regarding these?

I used the top one from scosche.
With that one you need to route the acc line to elsewhere. I just routed it to one of the relays in the fuse box, I don't remember which one, but it wasn't on any of the ign lines.
But apparently that one won't work, but audioroach hasn't been back to tell me why.
