The car does not matter, you will, or should have a wiring diagram for the alarm ?, or is it one of the super basic ones with just two/three wires ?
The most basic are just connected to the battery pos + and neg -, then one wire to the interior light circuit.
It would be much better to get a Toad Ai606 off the bay, as easy to wire in but far better protection, a lot more wires to do but easy if you take your time.
