2004 suburban

hello i need your help once againi need a wire diagram for a 2004 suburbanso if you can help please do thanks

Hope this helps, Diagram P.S. There's a shortcut for the doorlocks on the 4 door trucks and suburbans, beneath the B.C.M. there's a plug with a few empty slots, location B2 and B3 will work for unlock and lock, you can actually purchase the pins from Delphi, I've done a bunch of trucks pre loading alarms at a dealership, no problems to date, but use at your own risk!ASE Certified
