Any GM guys have access to pinout diagrams? I acquired a 99' 4x4 sub this weekend and have decided to put my 6.0/4l60E/transfercase in it. I am looking for the computer connector diagrams so I can hook up the speedo and 4x4 stuff in the 99' to the 2000 Z71 ecm. i wished I could Dmax it but the sub did't cost anything and I already have the drivetrain and I need a family travel vehicle.:thumb:
