I ordered my new Main Harness M-12071-C302 from Colorado Mustang Specialist. It says in the Ford Racing Performance Part book that It connects the Mass Air-Flow computer to the engine, sensors and relays, 26 page instruction book included with main harness. Contains very detailed instructions helpful hints and lots of illustrations for easy hook-up must be used with integral thick film ignition module distributor.

I asked the parts place and they said their was only one harness. There was no difference between the Automatic and a manual. When I did the AOD to T5 swap the harness was different if you used a manual computer with an AOD harness. Cutting the pin number 30 was how you solved the problem. I had Mustang Auto Tech do the work for me, because we bought a manual computer.

Why is there only one harness for sale by Ford Racing Performance Parts?
