Ya, got the complete package when I bought the truck. I will be installing a small compressor for air bags. So I’ll wire a relay to the Aux switch to turn it on and off. The actual power for the device will be fused and come from live posts where the plow fuse is above the right battery.

Maybe a dumb question but…I installed my GM upfitter switch assembly which was not really too bad. The trim removal is a pain. For clarity, the four blunt cut wires powered by the actual GM switches are simply to open a relay? I still need to get a power supply and grounds separately.

Perfect Exactly what I needed. Thank you! Chris

Ok, thanks. I’ll look at that.

Good day all….trying to install a camera in my 2025 3500HD. Need a key off unpowered circuit. Been through the left and right fuse boxes and it seems all fuses remained powered. Let the truck sit for a bit to eliminate RAP circuits. Have not tried the engine compartment fuses as I don’t want run a wire though the firewall. What am I missing here? Thanks for any suggestions!
