The inputs consist of 12v + and -, and an ignition switch regulated down to 5v. The outputs all drive relays thru transistors on the stamp board. They turn the relays on and off. The schematic is quite involved. I would sell a kit for $150 that had the stamp pre-programmed w/ just wires coming out a plastic box that all get hooked up like an alarm... One to 12+, one to 12v-, one to the ignition, and one to the computer switch and one to the computer power suppy and one to the monitor (if you'd like) I make my monitor come on after the computer boots so that you don't ever see the booting. I have a the stamp power an inverter that goes straight to an ac standard computer power supply.
