you will need a pats bypass for the remote start. you will have to do some digging and find one that matches the system you would like to purchase.
Personally i commend you for wanting to try this. But you should be able to find a place locally to you that installs remote starts. They can do it quicker. Know what they are doing. and shouldnt cost much more than doing it yourself.
Ive done remote starts before on non-pats cars (easier to do) its much more involved that just splicing a few wires together.
