Keyless entry install How-to

There is no button for the starter immobilizer. It switches on and off with the lock and unlock buttons. I would guess the wire for the immobilizer is hot when the system is in the "unlock" mode triggering the power to the starter circuit. Unfortunately, their isn't another trigger wire available. I think the remote supplied with the system is also used in some of their alarm systems and the red button acts as a panic button there but as far as I can tell it is only used for programming other remotes in this system. Sucks because I totally would have wired up a fuel door release. I always forget to push the button before I get out, lol.
