On the 4t60e park/neutral switch which one of the wires in the seven
wire connector do I need to hook up? Thanks

Check out the big yellow one.

Okay if memory is serving me correctly. the yellow wire goes to the C-500 the purple will go to the stater. These are the two bigger wires. There will be two wires for back up lights. I believe they are blue and light blue. Both go to the c- 500. Power to the switch and then back and on to the lights. The others are for things not normally used in the Fiero.

Thanks. I couldn't find that in my service manual.
