Direct from gm and plug and play

earlier in this blog there is a picture of the switch that has the three buttons and the extra buttons. I got mine from GM and it was a direct plug and play for my trucks options and I wired in the other switches to the fuse box. but you could go directly to relay. just remember that the switches supply ground and not power.

I thought the same about air ride and looked very hard at the wiring and it can be done. I would like to see what you end up doing

What is needed to make this change? do I need software or hardware or both can I just get HMI reprogrammed?

Does anyone know if it can be done

I have onstage nav but would like the maps. can you have both 2018 2500 GMC

Here is a new idea for a project look at the block heater plug on the 2020 hd where it is part of the fender .

I will keep an eye on it and if it moves I will make it stringer

please point me to this tpms trailer post

right now without the wires going to X61A the light work as advertised. they turn on and off when selected. each switch supplies a ground for the relays at X50a
