the wire, place the key in the drivers door cylinder. Turn it to the

unlock position and hold it when testing for the disarm wire.

The LED tester should illuminate and will extinguish when the

key is released.

When the correct wire has been found, strip a small portion of

insulation off this wire and solder the small LIGHT

GREEN/BLACK (H1/7) wire to this wire. Wrap the connection

with electrical tape.

Immobilizer Bypass Modules

Most newer vehicles have a factory engine immobilizer system

designed to prevent any unauthorized use of the vehicle. These

immobilizers will cut off power to the starter and the fuel supply

preventing a thief from starting the vehicle.

There are several types of immobilizers, with the most common

being the resistance based passlock/passlock 2 systems found on

most newer GM vehicles. This system can be bypassed using the

555L immobilizer bypass module available at your local retail

note: Any vehicle equipped with a factory immobilizer
must use an immobilizer bypass module to remote start.
If not used, the vehicle ignition or fuel supply circuits
could lock up and require a costly trip to the dealer to
reset the computer system.
