Yeah you can do it yourself, but be sure to do it right! If you have all of the wiring info, and some patience, go for it. Just remember to hide everything and tape all harnesses with electrical tape, or use split loom to copy the under-dash area to make it look stock. I have been an alarm installer for about 4 years now, and NOT 1 install that had been done by the owner that was not an installer, looked like all hell!!! By far, the easiest ones to disable. If you do it, take your time, and be neat with the wiring and connections. Our cars aren't too bad as far as wiring, not real easy to fry anything on the car. Most of the newer cars of the past several years have all kinds of control modules for security systems and locking systems and the lighting systems, not to mention immobilizers. These cars take a lot of care when taping into wires, but our cars aren't bad at all.
