1998 Cadillac Catera, Remote Start

1. Watch out what you buy over the internet and make sure that you are receiving full technical support and warranty from them if anything goes wrong with your installation. The price is not always the first thing you look at. Make sure that the system has enough features to integrate into the Cadiallac ( transponder bypass wire, tach learning, dome light supervision, etc )

2. Most of the cheaper version 2 ways are generic brands that suppliers get from the same manufacturer but put their name on it. Some brands that come to mind is Vampire, FM2007, Commando rage II.

3. The bypass is simple but you need a spare key to bypass pass-key III immobilizer.

4. Here is the wiring diagram:

Notes:

Note:  This vehicle is equipped with the pass-key III immobilizer.  *1 The BCM (Body Control Module) is in the passenger kick panel.  *2 The parking light relay is to the right of the steering column. Do not use gray/black, gray/red, or gray/green in the kick panel, even though they also test as parking light wire.  *3 The BROWN / white wire is in pin C12, and the RED / white wire is in pin D9.  *4 The factory alarm will arm if it sees an open door trigger when locking.  *5 The ECM is in front of the driver strut tower, in ECM housing. The tach wire is in pin 80. Can also use the ignition coil wires for tach. They are gray/black, BLACK / YELLOW, and BLACK/ red (they are heavier gauge wires) at the ECM.  *6 The theft deterrent module is mounted to the ignition key cylinder.  *7 Each power window motor is controlled by a module.  The module and the window motor are built together as one piece, not allowing access to the motor wires.  *8 The fuel door release is also a BLACK/ red wire at the relay behind the BCM, wire it as a 5 wire system.
