Hey,
I recently purchased a 1997 7.3 4X4 powerstroke that was converted from auto to manual.
After getting the steering column rebuilt the speedometer stopped working (dont know if it is related) but I also found out that the original wiring harness is still in place and is just tapped to accommodate the switch to manual.
I am also having an issue with a flickering alternator light and a delayed kick in of the alternator (when truck is started battery shows 8v then after about 30sec od driving clicks to 13v)
I was also told by seller that it has original auto ecu.
Dont know what I need to do? Replace wiring harness with manual specific harness? Change ECU?
Where would I get the parts, any instructions on the fix? Any recommendation for labor in the northeast?
Thanks in advance, Mark

Do a seach in the forum for manual transmission swap, a member here did one a couple months ago and he knows what wiring needed to be changed and stuff...

I'd go to a junkyard and find a manual trans PCM rather than doing it though the chip myself. The main difference in fueling between the 2 PCMs is the bottom end. The manual trans will fuel when it sees load from a stop(example-letting off the clutch), the auto PCM won't do that.

everything else on the truck should be the same. Only other thing I'd be worried about is the transmission wiring, but if that's not the same then it should swap over easily. the under hood wiring is actually kinda nice isn't it? it all comes out in one big chunk of wires and lays back in pretty nicely. Keep us updated on this thing
Did you look to see if the towers on the frame for the motor mounts are the same?? I'm kinda curious. I don't think they are so you will have to torch out the rivets like i did on the F-150. Since your not going on a spending spree wanting a basically brand new truck you should get done in no time. I coulda had the F-150 running a year ago if i didn't want every dang part brand new. It's a sickness, i swear.

i got the engine and tranny in last night all in one shot, not fun. most of the wiring is done, just some little add ons for the back doors and third brake light ( cause we all know if the third brakelight dont work, the engine will leak oil). i hope to be driving by the end of the weekend if this stupid rain holds out.
