  1. JamestownMike, were you able to figure this out? I just purchased a 2018 sierra with manual windows and am wanting to do the same you are trying to do. I read the entire post and it looks like you were off to a good start but then it ended. Just curious to know if you finally figured it out.
  2. I just did my 2001 GMC Sierra rcsb and I had the same issue. Your truck does not have the same wiring needed to do a conversion. You need to either come up with your own wiring and setup your own relay setup for the door locks and run all new wire for the windows. Or, you need to get the left and right junction boxes from a donor truck that does have power windows. Run new wire to connect both junction boxes together from one door to the other.
