That's why I said installation, not the equipment, is the key. Jim Bob who slaps it in with some vampire taps is just asking for problems down the road.
If I could find the alarm remote, the starter I put on the 1989 Toyota Supra in 1992 would crank the car just fine today. They're not rocket science. They apply power to 2-3 circuits and the starter wire for a few seconds. That's it. They don't even need a tach wire anymore.
The car is destined for an engine swap (LSx maybe) and I expect to keep the remote start unit. -- John M - Cranky network guy
