I just did the swap in my car, it is older 86 coupe , but same principles apply and possibly wire colors. Under the car in the tranny tunnel area you have your origianl AOD harness that plugs to the tranny, which won't work with a manual tranny. So what you need to do is find out which wires are for the reverse lights, and which are for the Nuetral safety switch, ony mine they are red/light blue wire and a white and pink, you just jump those so that it thinks it has completed the circuit or run a switch in the car as mentioned above and use that, once the circuit is complete it will put the power to your starter solenoid and then to your starter when in the start position.
