i dont think you will need any of the motor harnesses. you will need the stuff for the ac compressor and that stuf though

The lights aren't on the same line as the engine harness. It sounds like you have everything that you need for it to go carb.

Yes, ditch all the wiring...except the main harness on the drivers side...thats your dash lights,tail lights,dash components,etc. The headlight harness plugs into the main harness. You'll need to extend(or get a 5.0 alternator/headlight harness) to run the alternator on the passenger side. The stock 2.3 harness will work, just will run across the engine. Also, keep the heater vacuum that runs along the firewall. Hope that helps.

Depending on if the car is an auto and converting to 5spd. The speedo cable will need to be re-routed. Theres a plug that has to come out, speedo goes there, while the old speedo hole becomes the clutch cable hole. The speedo cable from the 2.3 and 5.0 are the same, however, where the cable attaches to the frame rail theres a ring/sleeve on the cable. You'll need to slide this sleeve down about 3 inches to gain some length so to say to the instrument cluster and reaching the tailshaft.
