Get a 5spd pcm and harness i did and have had no problems. Just make sure They're both from the same year as your car.
I looked for a harness for 3 months before I did the swap and I am still looking. Can't find one anywhere.

Not so easy in California. The only thing I can find is V6 cars. It's like the Gt's have fallen off the face of the earth. No one has parts for them listed anywhere. My Clutch pedal assembly and hydraulic line came from a V6.

Okay not sure what year yours is but in mid 2006 the C110 connector changed shape. Its the big plug that connects to another harness near the pcm. Hopefully the one you purchased matches yr existing one and everything plugs right in. If not you'll have to cut the connector off and solder the other one on.

Mine is an 06. If the connection is different, I'll just change the plug end as long as the wires are the same. Thanks for the info.

MY SWAP IS DONE! I did it over Thanksgiving weekend. It took me and my dad two full days of work, from sunrise to sunset. it was def. worth it. shes running like a champ! :) i did it with the help of this write up and one from this website Auto to Manual Swap - The Mustang Collective Forums also the service manuals on the top of that post helped alot. I want to thank you anthony your write up was very help full also to temugen from the mustangcollective.
If anyone has any questions or need adivce about the swap id be happy to help. To anyone thinking about doing it, its not hard but you need to be some what mechanically inclined. any DIYer with the right amount of research can do it.
just giving back to the community. :)
By any chance could you list some of yhe challanges you came across. I just finished pulling everything out. Purchased what i think is everything and am about to start this swap.

You can reuse the same cross member. I actually did this swap last fall, thanks to Anthony's write up. As a note, I've got an '06 and I replaced the wiring harness and pcm from another '06. It did require a tune to get it working properly, but no issues and with proper tools and a lift, I was able to complete the swap in a day.

Thanks for leading the charge on this so many years ago Anthony
Did you have to modify your harness on your 06 or did it sawp with nonissues. I just got a different harness and 1 plug is different shape then on my harness. Its the plug near the pcm plugs. Im hoping the guy just gave me the wrong year by mistake

This was 8 years ago so It's kind of hard to recall any specific issues that I had... But from what I can remember I didn't have any specific issues. Mainly just available space for work-ability, especially using only a jack and jack stands. I would suggest reading the written guide at least 100 times. Send me a PM if you need anything and I'll give you my email. I don't get on here very often...

is it possible to replace the smart junction box with one pulled from a manual car to get the reverse lights working correctly without having to run all the extra wire?
might it also be possible to get Cruise control to work correctly that way also?

Im trying to swap a TR6060 in and I'm wondering the same thing. Did anyone get the reverse solenoid to work/cruise control/reverse lights? Seems like a stupid question but its kind of confusing.

I have both a set of auto and manual PCMs/engine-trans wiring harnesses. But I don't know if I have to swap them and I would prefer not to if I didn't have to.
