OK. got a few switch banks and combined switches to match my options. Now I've got to pin out the connector to figure out what's what. Once I know which pins cover which functions I'll be able to hook everything up correctly. It was a real nightmare getting the switches out of the housing. My final configuration is all momentary switched with a board from GM part number 23145202. It originally had pedals, stability, cargo lights, park assist, lane keep, hill assist, and exhaust brake. I don't have lane keep, hill assist or exhaust brake as options on my truck, so I replaced those with three aux switches. I think it's going to be a bit of work to figure out the pin outs. It looks like every version varies some, but I'm hoping that there's some commonality at least with the options I do have. That way those items should work just like before when i plug in the new switch bank. I just have to figure out which pins go to the other three switches now and if there are led returns. I know the exhaust brake is going to be on the smaller connector on the back, so it's just aux 1 and 2 I need to identify.
I'm hoping the pin out looks like this
