if something happens from the alarm system or central lock then this part only will get you out of warranty....
but to play it safe....go and install both at clarion.....
and ask whoever will install the stuff for you to take the power of the alarm from the back of the cassette unit....
let him remove it and there will be an AUX power in the back....let him take the power of the alarm from the cassette....that way you will eliminate the guy from playing with the electrical defera.....
