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

how hard is it to add it and keep what I already have. can anyone tell me if I can add nav to my existing 2.5 hvmi

can anyone tell me if I can add nav to my existing 2.5 hvmi

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

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

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

ok I see this would make sense if you use aftermarket relays but I plan on using the factory upfitter at X50a not sure how I could add these diodes. the latest ui bulletin states to delete earlier bulletins I'm looking at 110m. Do you have a source for the terminals maybe you could sell me some so I could run all the wires from s48a to X61A then x50a and some extra as I also want to retire my second fuel pump relay for my off road lights

again why the diodes as they are not in the factory drawings. also I know I could go around X61A but I really don't want to. if I could get the terminals I will make the wires
