I have a 2018 Chevy 3500 HD with aux switches on dash. Where are the wires from switches stored? What color wire goes to which switch? Are the switches on battery or ign?

There should be some information on the auxilary switches in the Owners Manual. My Ford SD has it.

You can also pull down the Body Builder's Manuals from the GMupfitter website: https://www.gmupfitter.com/pages/body-builder-manuals

There are likely other docs with the info on the GM Fleet website.
