Notes:
NOTE: Some models have an immobilizer system that needs to be bypassed during remote start. Use DEI module 555F or 555U to bypass. *1 Unlock requires a double pulse. *2 The individual door trigger wires are at the passenger side junction box behind the glove box. The driver door trigger is RED / yellow in a 10 pin plug in pin 3, the front passenger door is RED / white in a 20 pin plug in pin 5, and the rear doors and hatch is RED / white in a 10 pin plug in pin 2. *3 The data link connector is below the driver side fusebox. The tach wire is the black wire in pin 9.
If it's not custom, then it's not you.
