I need help, harness and trans are from a 2000 yukon XL 2500 on the trans there is a neutral safety switch, on this "NSS" There are Two connectors. (which are ****ing GLUED in) why do they glue them? 3 harnesses I have done up were all glued! Anyway, the bottom connector has Four wires. BLK/WHT, WHT, YEL, GRY. These wires are from the neutral park switch to the PCM. the top connector has ~6 wires 2 PINK 1 PPL/WHT 2 LHT GRN 1 BLK WHERE DO THESE GO? These wires don't go to the PCM they went into the cab. I have searched tech with no luck. one should be a TCC to brake pedal? or does the TCC come from pin 33 brake switch on the blue connector?
