03 Tahoe alarm OK guys new here I have a 96 Tahoe and I just got a complete 03 motor with harness and computer my only question do I have to delete the passkey system off the ecu or can I leave it? I will still be using my factory ecu to run my abs and gagues ive read up on this swap but haven't found anything about dealing with the alarm
