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 The BECU (Body ECU) is behind the glove box, it is the module to the right.  *2 To avoid the dome light delay, go to the Body ECU behind the glove box to get the individual door trigger wires. In the 19 pin plug, the driver door is RED / blue in pin 11 and the rear hatch is WHITE/ red in pin 6. In the 17 pin plug, the front passenger door is RED / blue in pin 16 and the 2 rear door is red in pin 15. Use all wires and diode isolate each.  *3 This is the key sense wire for the ignition switch. The wire changes colors after a junction plug. It is red on the ignition switch side and blue on the other side. Using the status output wire from the remote start to ground this wire will disarm the alarm without unlocking the doors.  *4 The ECM (Engine Control Module) is behind the glove box, it is the module to the left.  *5 The amplifier is under the rear load floor.

Is up to the installer to test all wires with a DMM whenever possible.
