How hard, if even possible, would it be to set up a remote for a 89 Mustang GT, that has lock, unlock, and remote start on it? Not really going to worry about an alarm as I do not live in an area where many cars are stolen.
I have keyless entry and it's great. I bought it from JC Whitney for around $40. My dad and I did the install. We pulled the door panels to trace the wires to under the steering column, which is where we put the box. It needs a constant hot, so we spliced into the one for the radio/CD player. The hardest thing to do is accessing and splicing the wires up in the driver's side kick panel area.
I really want to do the remote start thing, so I can just crank the car and let it warm up before I head into the woods in the morning, or before I head to school.
