yeah, i know about the valet switch and how to program and reprogram remotes. i did it with the remotes it came with. so if i got a new clifford or avital alarm(whole system) what would i have to do to install it? just switch out the brain or rewire it or what? its a avital diablo2. so if i got like a generation 4 alarm from clifford, would the harnesses be the same? i would like to be able to do it myself. ive done all the electronics on my car except for the alarm.

do you recomend getting a new alarm anyways since mine is about 4 years old?
