I have my Canyon set up to tow and ensure it's in Neutral before I begin (page 255 in the manual I think). The light on the transfer case switch tells you when it's in "N" and they give you a procedure to follow (see below).I need to send a signal from my Chevy Colorado diesel FWD to the cab of my motor home. I need this signal to ensure that the transfer case is in Neutral. GM has left me high and dry for support. Same with local dealership.
