I have a 2005 Silverado 2500HD. I am looking for a wiring diagram for the overhead console/map lights. I realize that the harness connector can have 2, 3, or 5 wires. My book seems to only show two wires, ORG and BLK/GRY. I need diagrams for a 3 wire and a 5 wire connector. The post for the mounting screw on mine suddenly decided to snap off right under the fluted section and started to break at the base of the post where it meets the body of the console. I have repaired it with liberal application of 2 part epoxy and epoxy putty. If that does not hold, I will need a new console. What I have found online in the right style/color have been with the 5 wire connectors. I may have to make a 3 wire to 5 wire adapter from the 2 harnesses and need to know what wire is what and if the color codes are consistant. My console has the shelf, two map lights, and 2 on off buttons. They turn on when the doors open (courtesy lights) and can be turned on/off with the buttons when doors close. Thanks

 

Hopefully you can zoom in far enough to read the options. The wiring coming from the left side of the diagram runs straight to the BCM - there’s no direct power or ground circuits.

 

Thanks. That explains the 3 wire console I currently have. The orange looks to be the circuit that turns on the lights when the door opens. Gry/Blk looks to be the switch circuit. Hopefully someone has the 5 pin diagram
