Installing a CG 745i in my '04 Silverado LT 2500HD diesel crewcab. Everything is connected and working except the door locks. Does anyone have wiring info (color / location) for this truck? I am wanting to use driver door priority unlock. The 745i has two internal relays and the wires are listed below.

Violet - Unlock (+) or (-) Input (NO)

Blue - Unlock Output (COM)

Brown - Unlock Input (NC)

Violet / Black - Lock (+) or (-) Input (NO)

Green / Black - Lock Output (COM)

White / Black - Lock Input (NC)

Pink - Unlock #2 250mA (-) Output

Thanks in advance! Pat

-i think the 03-04 are similar truck. on the based model truck, the lock wire is lt. blue (-) and unlock wire is white (-). They are in the lt. blue plug at the BCM. if not based model, look at the pdf

-so the wire above youll need:

Violet - Unlock (+) or (-) Input (NO)

Blue - Unlock Output (COM)

Violet / Black - Lock (+) or (-) Input (NO)

Green / Black - Lock Output (COM)

-----

-look at this pdf file
