Ignition Switch Wiring?

[ak47]

I just put a 305 TPI motor from an '86 Trans Am into my '85 pickup and I haven't been able to find a diagram or explanation on how to hook up the ignition switch to the T/A wiring harness/motor. Can anyone tell me where the run and start wires from the ignition switch go, and anything else I may need to hook up for the ignition? The ECM # is 1227165

Thanks.
