not anyone, i drive a mustang and supra and i help people on both forums and the supra club in our area

mustang alarm i can do in 30 minutes a supra or toyota are not that simple,novice installers don't know what a double pulse locks are and why they have to test the wires from the passanger door on some vehicles
ford mustang is very simple but yes i have seen installers wire the relays for the locks with out a fuse and then you have to put fan in the vehicle for 20 minute to get all the smoke out
