I didn't get the harness with it. I bought the GReddy timer and it says that if you have 2 ignition wires you hook both the green and blue wires to each one of the ignition wires and the last wire to a constant 12v. I'm hooked up both of the wires to the ignition wires, but when i turn it to accessory it works fine, but if i turn the key to lock and take the key out the engine shuts off. Anybody know exactly what wires i'm supposed to hook up to????? Or if i did anything wrong???? Thanks alot....

I assume this is no different than a stereo. In which case I would hook both the grean and blue wire to the ignition (not the acc) and the other to a constant 12v supply. When I did this to my stereo back in the days. It would allow me to turn on my stereo system without having to stick the key in or start the car.
