GM Wiring Connector - Bed Lights

[Rob R]

Good Morning All - 

 

I am looking to make a custom harness this weekend and tie in some bed lights and rear flood lights on my new 2018 Silverado. I bought the parts that ETEXEMT posted in order to make the custom harness, but I am not sure which pins I should connect the Neg and Pos wires to. 

 

Here is my unwired 6-pin harness Plug:

Here is the DIY on an 8 pin plug from CBRSILV15

 

Thanks to both CBRSILV15 and ETEXEMT for their posts on this -

For $25 or so you can get a factory harness and modify the ends on each side to fit what ever you are doing. You'll get a better terminal seal under the vehicle.

$26.57 for the harness, but it’s another $20 for shipping.

Used the harness to connect 8 pickup bed lights and tied in two Nilight LED driving lights under the rear bumper.

 

Harness worked great. I had to modify the ends and crimp on butt-splice connectors, but everything worked the first time. The harness is directly  tied to the cargo light switch on the dashboard.
