    Early dual mass starter on late model car (need help!!)

    Ok so heres the deal, I have a late model i car that used to be auto, but i pulled an entire five speed swap from an eta at the yard. It has an early model dual mass starter. The harness has three wires going to the starter originally, but the eta one only has 2.

    My question is, what do i need to do to make this work?

        Early cars (through 8/87) had two wire starters (main power and solenoid). Late cars have a three wire starter (main power, solenoid, and unloader relay control). the unloader switch in a late starter grounds the control wire when the starter isn't engaged. Early cars have a fixed ground for the unloader relays. You can use the three wire starter in an early car (the unloader connection isn't used). If you use a two wire starter in a late car you can just ground the unloader control lead to have everything work. If you use a late harness in an early car with a two wire starter you can ignore the unloader wire.
        The car makes it possible, but the driver makes it happen.

              It's not even in the car yet. But I knew it was a potential problem so I posted the thread.

                  Ok so I got the motor in the car an I'm having some trouble getting it to crank. Battery is charged, I think the nuetral kill ignition switch wiring is done right (posting pics to make sure) and the motor ground is on. I need help! I do t know where the 2 smaller wires near the starter harness go. Onto pics to help:

                  Nuetral switch wiring. Does this look right?

                  And here is my starter wiring. Anyone have a clue? Lol
