Sorry, Jeff. ISC is Initial Set Connector. I believe that is the standard term. It is the single green plug near the battery/main fuses you ground whenever setting the idle. We had it on and off so much when doing the swap I made a wire with a male spade and a ring terminal. But even though it was attached to a cleaned bolt holding the main fuses to the shock tower it wasnt delivering a good signal to the ECU.
The fast idle adjustment needs to be set so that when the engine (well the wax) is cold the green topped drum is aligned with one of the marks on the cam and when hot (the piston rises) the green topped drum is aligned with the other mark on the cam.
Good luck. It gets better!
