GREEN (-) @ DRIVERS DOOR MODULE, IN DOOR, BLACK 26-PIN PLUG PIN 15 ANTI-THEFT GM'S PASSLOCK 2 ANTI-THEFT SYSTEM, SEE NOTE #1 @ IGNITION SWITCH EXTRA INFORMATION NOTE #1: This vehicle uses GM'S PASSLOCK 2 ANTI-THEFT SYSTEM that requires a 791 Bypass Module to Remote Start, if you are using a REMOTE STARTER ONLY, use the 791. IF you are installing a REMOTE STARTER with KEYLESS ENTRY you MUST USE the INTERFACE BYPASS MODULE, Part # DB-ALL or XK09, EITHER Bypass will do the Anti-theft and Keyless entry. If connecting a keyless entry only you can use the GMDL-BP. NOTE #2: The IGNITION #2 wire WHITE must be connected to prevent a CHECK ENGINE LIGHT from turning on and to prevent DAMAGE to the TRANSMISSION on this Vehicle. NOTE #3; The BCM is located under the Drivers Side of the dash, the BCM has 6 plugs on it, with the PURPLE plug on the back. NOTE #4: On BASE model truck the DOOR LOCK INTERFACE MODULE is not necessary, the LOCK wire is a LT BLUE (TYPE B) @ the BCM, LT BLUE PLUG, PIN B5, and the UNLOCK wire is a WHITE (TYPE B) @ the BCM, LT BLUE PLUG, PIN B10. NOTE #5: On BASE Model trucks, the Door Trigger wires are @ the BCM, LT BLUE PLUG, PINS B4 and A5. On 4-Door Trucks the LEFT REAR Door is a LT BLUE/BLACK (-) PIN A3 and the RIGHT REAR Door is a LT GREEN/BLACK (-) PIN A2, located in a PURPLE PLUG at the BCM, use all 4 wires and diode isolate when installing an alarm system.

Have you had work done in this area recently? If not then its possible it doesn't connect to anything on your model.
