All you have to do is add the power wire and the fuel pump wire. The instructions are very clear and simple. I tried it this morning and the pump ran with the key and the engine tried to start but then fuel pump quit and i lost spark. Very frustrated as i bought a new preprogrammed pcm from PSI when i bought the harness for a trouble free start up and no need to have someone else tune it. I have quadruple check all my wiring so it looks like a call to PSI and bring home a scanner from work monday.
