98 mark viii to 98' f150 motor swap
Hello everyone,
Im slap dab in the middle of swapping a 98 mark viii 4.6 32v intec and putting it into a 98 f150. The truck HAD a 4.6 triton w/auto trans. So now Ive got both motors and transs out, and I know I will need the ECU from the mk. What other wiring will I need to take? Im using the trans that was in the f150and the mk motor. Anybody done this before? What other roadblocks will I encounter?
Any advice will help.
thanks

you only need the engine harness, I am unsure why everyone is so dead set on swapping ECM's when they don't need to and it only brings on other issues when swapped...
you need to pay attention to the torque converters / flexplate interchangability as the car converter won't be happy in the truck and the truck flexplate might not bolt onto the 32 valve motor

I owned a 95 Mark VIII for 9 years and I loved that car!

I don't no about that, - manipulating the original PCM would be choice. Unless for some reason,- it can't be ? I can't think of any. Using the Mark comp COULD cause a lot of other issues that are PCM managed. Personally, I'd confirm with the tuner to be absolutely sure. Uknow, -what's easier for him.

if it's not, then get a vacuum controlled box and be done with it

tarajerame, I was under the impression a 16valve ECU would not control a 32valve engine. Am I mistaken?
Also the transmissions/flex plates/converters will all work in my application, good looking out on that though, its one of the first things I checked.
