boomer, thanks man.  I am hoping to get ahold of something more in depth. in relation to the door trigger output,  dome light input, wire colors etc....  for example here is a link to the 2002 Trailblazer that was posted recently - https://www.directechs.com/directwire/wire_body.asp?action=select&yr=3423&product=Remote%20Start

door trigger output is listed as alarm input wire. Gray/Black.   Domelight appears to be the same.
