Hello all I just purchased a 2002 Jaguar S-Type 4.0 and I have a question regaurding the installation of an alarm, and I figured this would be the place to ask. Well, I was wondering if anyone know of a site where I can find a wiring diagram or even a chart explaining the colors of the wires. Also, I was wondering if I had to put a spare key into the alarm in order for it to read the chip. Any help regarding these matterswould be greatly appreciated. Thanks for your time.
