No you will need to get the harness for the from the manual. And have a tune written that shuts the auto functions off in ecu.
There is no need for a new tune. It wont change how it drives. The only thing that needs to be changed in the tune is oss for the speedo to read correctly.

Also, you dont need the steering column. If you switched keys, the key would no longer match the gauge cluster and ecu.....therefore pats wouldnt allow the car to start. Bama cant tune for that. Also, id recommend getting a real tune rather than piss poor canned tunes from Bama.

I'm still driving mine with the auto harness with the neutral safety switch zip tied to the side of my 3650

No speedo, and no reverse lights, but it runs like a factory manual



A bit of advice for what I mentioned before about extending the 3650 harness; Take your 3650 harness, compare it to the 4r70w harness, and make a manual harness out of the longer automatic one. It's not hard, you should just need the connector off the 3650 harness for the reverse lights and you're solid.

That's only if the 3650 harness doesn't plug right in your car, there's no need to mess with it if you can just plug the 3650 harness in and go, just wanna clarify on that.

It will plug right in to the engine harness. Im actually using my old t45 harness with my 4r70 since i did the opposite swap. lol. I have speedo but no reverse lights. I should wire those up but i really dont care.

Actually if you're like me, it won't. The connector is the same, but the 3650 harness I got with my trans out of an '03 Mach1 stops on top of the bell housing, whereas the connector in my 99 GT is behind the shock tower as you can see one page back, so the 3650 harness I got simply won't reach the plug.

I think Ford may have made too many different damn harnesses for 99-04 transmissions.

Negative. I swear it on my life, at least some of the 99-01s have longer harnesses because my GT and my brother's '01 v6 is in the exact same spot and neither had been touched or modified in anyway.

His is a factory manual and mine was a factory automatic GT.

Same exact date my brother's v6 has

As I said before, you can modify your auto harness super easy.


[Pic is of the '03 3650 harness]


See that looped red wire? That's your neutral safety.

[Auto harness]


Just loop that red/blue wire together on the auto harness with the white/purple and your car will now start.

Then all you have to do is take this connector off the 3650 harness and run the black/purple, and orange wire to it and there's your reverse lights.



The auto harness already has the speedo connector so that's literally all you need to do.

You can also remove/cap off the extra wires if you want for peace of mind. To my knowledge leaving them won't change a thing.

If he doesn't turn of the automatic function in the tune he will get flashing overdrive light. The auto ecu will be looking for a singnal from the EPC seliniod which isn't present in manual transmission. Will it effect how the car runs no but the flashing od light will be quite annoying

See where the trans harness comes off off the engine harness? There is so much slack there you can put it on top of the bellhousing.


I will have to look into this, I had my engine out and I could swear there was no way to make it reach the harness I had.

I posted pics a page or two back.

Here's a factory manual harness. Notice the looped wire:



And here's the auto harness. You're gonna loop the white/pink, and the red/blue wires, or whatever wires are in that position on the plug on the trans harness. Don't cut up the car's main harness as it's not nearly as easily replaced.



And here's the location of that plug on my car, but yours may be down on the bell housing depending on the year of your car.



That little loop will bypass the neutral safety switch that goes on the side of the auto trans, and your car should now start.

How do we get the tr sensor (neutral safety switch) off the old tranny?... my buddy did climb under the car and cross the selenoid on the starter and got it to crank that way.... but fuel pump isn't coming on either... I'm sure it has something to do with the round connector next to the square one on the auto harness and the auto main harness that the manual tranny harness they sent me dosent have...I'll try to get this thing to post a couple pics I have of the auto harness and manual one so can see the connectors I'm talking bout.. the harness on he left is the auto and as the round connector my main harness is wanting... the left is the manual harness they sent me with my swap parts... it's missing alot of wires the other had... I kinda wonder if they didn't send me the wrong manual tranny harness

Well I changed the engine harness to a manual engine harness.... had the same issue so I changed it back to the auto engine harness and tranny harness and did it your way and put a jump wire between the pink and blue wire, and the white/pink wire.... now the car cranks but my fuel pump isn't coming on at all... theft light flashes while cranking... any ideas what could be?? I checked the inertia switch and it is not tripped

Hmm, weird.

Alright first: What year is your car?

Second: Have you changed the steering column, ignition switch, gauge cluster, or ecu?




This is the neutral safety I was talking about



What I did (Yes I realize this is shade tree, but I'm not selling my car to anyone, end of story.) but what I did was remove that from the side of the auto trans (just bolts on) and put it in the neutral position (I believe it's 3 clicks to the right on a 4r70w) and I ziptied up out of the way beside the new manual trans. Car fired up perfectly, and has been running and driving great and healthy for 2 years and 2 months, only con is I don't have a speedo, or reverse lights, but this is a temporary solution even for me. I just don't have access to a tuner to fix it right currently.
