I have no idea what this component is? I am swapping a complete drive train, engine, harness, rear end, all electronics, etc from an 03 mustang gt and for the life of me cant remember where this goes, help! Does it have anything to do with the security flashing on the dash? I ran the car before disassembly and everything functioned fine but now no start. Its all going into a 46 Ford Panel Truck.
