the ford muscle article on the swap stated that I would only need the one small wiring harness and showed a picture of it next to the cross member/ exhaust mount and I am wondering where I would find this harness? Was it already on my car with the AOD or does it usually come with the T5. I purchased a new ford racing T5 heavy duty so I don't think it will come with any wiring. I was told by a gentleman who deals with these swaps that I need the WHOLE T5 wiring harness which looks more like a tangled ball of yarn than anything else. Please help!!!

I just did mine. You only need the short harness for the back up lights. I bought the whole nine yards on Ebay. Keep checking Ebay, www.latemodelrestoration.com. AOD harness is useless on the T5. Some T5's also come with a neutral light switch, top driver's side, don't bother to use it, just let it hang if the trans has it. Also don't change out the cpu or ecm.

Thanks a ton. I just bought the small harness on ebay I think it will work great. Are you happy with the conversion or did it feel sloppy and rigged?

I can't speak for others but I'm very happy with my T5 swap and a total blast to drive compared to the AOD. I don't know what you mean by feel sloppy and rigged... the transmission? the whole drivetrain?

Anyways, I got most of my hard-to-find parts (clutch pedal assembly, back-up wire harenss, etc.) from eBay and I didn't need to chaged over to the T5 wiring harness and I kept the AOD computer. In fact, I was told that AOD computer is actually better with a T5, I guess more aggressive timing. I also recommend upgrading to a aluminum clutch cable quadrant and driveshaft.
