Google gm upfitters.

All wiring diagrams are there. Although I don’t know if they released them for the new models yet.

jwyman,

What were you using the wiring diagram for?
I just bought a 2019 Silverado Custom Trail Boss and I was pissed when I found the center front jump seat had no storage capability.
I picked up a jump seat from an LT and swapped it in but the LT seat has 2 USB and 1 - 12 V power port that I don't know where I can get power from for it. The Custom Truck floor wiring harness does not have a place to connect the jump seat harness.
Any chance you were doing the same thing and found out how to do it?

ferraiolo1,

Thanks for gmupfitters website. That place has a great amount of information for these trucks. I'm just bad with electrical so I am hoping someone has done this already and knows of a plug and play option I can copy.

Thank you.
