'02 caddy deville alarm/remote starter

Anyone install either an alarm or remote starter or both on a '02 Caddy Deville? Any tips or things to look out for? Gonna be using the Xpresskit CANMAX400. Should be pretty easy if im using that right?

Thanks in advance.

Thats good to hear.

I read the wiring on this car. Says it has 2 ignition wires and 2 accessory wires. I worked on a Monte Carlo the other day and I had to wire in a relay for the 2nd accessory wire. Should I do the same thing with this car?

For the parking lights...should I wire in a diode? Had to on the Monte Carlo. I know these GM vehicles are alot different than what im familiar with.

Thats about all the questions I have.
