Camaro/Firebird DRL Module color codes
Apr 10This is just a quick note for myself others might find useful, since I didn’t have much luck searching for it in google. The wiring schematic is in the HELM Factory Service Manual (part# GMP00F – $135) but the pinout is just as useful:
DRL Module Pinout:
Connector C1 (8-pin black)
A – Orange – power from TAIL LPS fuse
B – Light Blue – left front DRL/turn signal lamp output
C – Dark Blue – right front DRL/turn signal lamp output
D – Red – power from headlight switch
E – Light Blue with White – left turn signal input from turn signal switch
F – Yellow – power out to headlights via highbeam switch
G – Dark Blue with White – right turn signal input from turn signal switch
H – Brown – parking/running light output
Connector C2 (8-pin blue)
A – Black – ground
B – not used
C – Pink – power from GAUGES fuse
D – Tan with White – brake warning indicator output
E – Light Blue – parking brake switch input
F – Brown – power from TAIL LPS fuse
G – Light Green with Black – ambient light sensor
H – Yellow with Black – ambient light sensor
Here’s how to disable the DRL on 1999, 2000, 2001, 2002 Camaro and Firebirds without completely cutting it out or unplugging it. Personally, I’d use the switch option instead of the jumper.
All of this, in the name of bastardizing/improving/automating/modernizing the lighting system in Otto.
