Thank you. That's the best data yet. So I performed a test yesterday using just 16 ga wire in the connector body to see if I could get the light relay to work as I already the auxillary upfitter switch. No luck. The aux switch LEDs would light indicating they switches were on but relay for light bar would work. Other threads and YouTube vids stated these switches close to ground and that's how I wired the relay to switch the ground. I checked switch to ground function with a multi meter and it did indicate ground most of the time. Sometimes when grounded woul lose LED indicator function on switches. I'm fed up with trying to get the upfitter switch to work so sending back. Unfortunately can't send back the 13575783 GM wires.

Thank you for this info. Frustrating trying to figure out terminal type and size. Hard to find specs for the terminals. Wish the DigiKey site had an image for reference. Will keep my fingers crossed.

I purchased the GM 13575783 wire kit to use for the Aux upfitter switches so I could install an LED light bar. The wire ends do not fit into the connector body. Anyone else have this issue with a 2016 Silverado?

Thank you. Was thinking of wiring that way.

Where would a good source for LED light bar power when truck is running for 2016 Silverado? Also would anyone know part #for wire terminal when installing an auxillary upfitter switch. Thanks in advance!

Thank you.

Will 20 inch 2021 Silverado Rims fit a 2016 1500 Silverado. Thinking of replacing my 17 inch rims on my 2016 Silverado with 20 inch 2021 Silverado rims.
