So the intermediate harness idea sucked. Many of the wires didn't match up so I started moving pins and stealing pins from the V10 body harness and then I realized that meant I couldn't rely on the V8 ECU pinouts matching up with the V10 harness. Duh...
So, back to the V8 harness - I had two so my original is still intact. I bolted down the intake and installed the coils then started to see how things looked and ran into another snag. The fuel injector plugs on the V8 are different than the V10. I have snipped all the injector connectors off the V10 harness to solder to the V8 harness.
I have also done little stuff like install the starter, torque converter nuts, (glad I remembered to swap my 4 hole flexplate from the V8) transmission to engine bolts, oil change, transmission fluid change, throttle body cleaning, and front accessories.
The A/C compressor is very close to the idler arm bracket, but I think it will be OK. ***EDIT: It's not OK!*** Same thing for the IAC after some bashing.
I made a spreadsheet of what pins I'll need to move around at the ECU to work with the V8 harness. It took some thinking because COP 1 on the V8 harness is no longer COP 1 when used on the V10. I made a little illustration to help me keep things straight. I'll update the pic below as the project progresses if changes are made.
did you use a V8 engine harness or did you use a V10 engine harness
Question that I did not see addressed, partly because I'm sure there aren't many still on the road. I've got a 1997 F150 with a manual transmission. How will it stand up or should I look at trying to find a complete drive train? Finding a manual is beginning to be a PITA.

that's a mazda light duty transmission, it's rated for almost no torque at all
I'd look into a ZF swap but it won't be beginner friendly
If you presently have a V-6, the transmission will not bolt to a V-10. The V-8 transmission will, but it cannot handle the torque of anything bigger than the 4.6 it came with. You would need to find a ZF manual from a V-10 Super Duty (same drive type - 2wd or 4wd), a custom driveshaft, and will have to do a body lift or cut out a large portion of the floor hump.
Thanks, no the truck has the 4.6 in it. I had already considered a donor vehicle with a complete drive train and a body lift to help with the clearance issues. Ran into the same ones putting 302 into a Ranger. Again thank you for the feed back.
Well, the F150 is getting some attention. I'm moving back to AZ, so soon, the V10 will haul a 16ft trailer across the country. I fixed a bunch of little things and next month it gets tags again.

Glad to hear its still hauling! I ended up picking up another f150 and 4v swapped it instead of v10. Both are unique swaps. Hope you're doing well!
Well, the truck made it across the country, but we had some trouble. A U-Joint failed and destroyed the rear yoke and the rear of the driveshaft about 100 miles from El Paso. Short story is that we drove in 4x4 to a junk yard where every driveshaft was bent because they load the vehicles in with a forklift. We bought a bent driveshaft then drove in 4x4 to a Harbor Freight. I bought a welder, a grinder, an extension cord, and a flashlight. We chopped the rear off the bent driveshaft and welded it to my straight driveshaft in a grocery store parking lot. I still need to find a driveshaft, but this one is holding up!
Side story, I was hospitalized as soon as I got to Tucson because something bit me on the wrist the day before we left Florida and by the time we got to AZ, I had a huge mass on my arm which felt like it was broken and my hand was swollen up too. I spent 4 days in the hospital on IV antibiotics for MRSA. I have gory pictures, but I don't know if they meet site guidelines.
I have a 2006 F150 that I am seriously considering doing this swap too. I have a 3v 5.4 with a 4r75 but I have had non stop problems with my engine, and it's nearing the end of its life since it's hitting 180k. It's either this or a 4.6, since I live in NY and I doubt a diesel swap would be legal. My 5.4 needs a timing job (I think i have at least 1 or 2 roller followers that are bad) and I am going to have to pull the heads on it to replace the stupid manifolds because of so much salt in New York. I really want to throw the 5.4 3v off a cliff because of all the issues they have lol.
Just for the sake of curiosity, would it be easier with a 4.6 2v ECU to do this swap, or how could I get it to pass OBDII emissions? Or how could I use the 5.4 3v ECU? Also, do u have any more wiring information?
I'm looking at maybe a 3v version of the V10 if I can find one and then a ZF5/ZF6 behind it, with of course the 3in body lift. I am sick of my 4r75e and it's due for a rebuild or to be replaced because it's shifting hard and wierd (lag when upshifting?)
I would get the same gas mileage as I get now or better with the V10 considering your numbers (I get 12-13 highway and 10-11 city driving) which is pretty awesome considering it has 2 more cylinders. I don't really tow much but I do constantly haul around tools and materials for work.
Also, are there other v10 swap build threads? I'm trying to get as much information on it as I can.
I did consider a 4bt swap or a 4.5 Powerstroke/VT275 swap but those are hard to find and 4BTs wouldn't meet the same year or newer requirement. I'm basically just trying to get as far away from the VVT crap as I can and build a reliable truck.

Would a 4r75 hold up behind a V10? What I might do is use the 4r75 for a while until I can set aside some money to do the swap the ZF5 or 6 in.
I'm looking at 1500-2000 in parts to do a timing job on my 5.4, so this swap seems like it would be pretty worth it considering 3v V10s are going for 1500-3000 with 100k miles on em or less.
