I would be interested in seeing what you do for motor mounts. Are you going to utilize the stock mounts
Thanks

here is what I think the harness mod info is.. the green rows are remove (not many, rear o2 sensors, egr sensor, ...)
assumes u are using the normal 4r70w auto tranny too.

this has 96/97 (coil pack), and 98 on (coil on plug) (all DOHC only)

(this is a spreadsheet, but I can't find a way to upload that, so these are PDFs of the two sheet tabs)

let me know what you think, and any corrections if u try before I do.

Thanks for the post on the wiring. I just received my wiring diagrams in the mail on Saturday, so this is useful information. I am thinking of attacking the wiring next, so I will keep you posted.

This Thread just sort of died. Did anyone get their 4.6 running? Any problems with the ECM i.e. needed a tune, what must stay and what doesn't??? I'm planning on installing a 4.6 this spring in my 56 Panel and am researching the process to have everything I need ready for the Thaw

Thanks in advance for any assistance.

I have not finished mine yet. I got about 1/3 of the way through the wiring harness an got board and moved on to more exciting things. There are a ton of wires in that harness! I will probably pick it up again in a month or so and see if I can finish it

Are you trying to use the entire harness? I'm debating on just trying to use the engine harness.

Yes, I am planning on using as much of the Mark VIII harness as I can. Be aware that the transmission and the fuel pump run off the interior harness. When I pulled the engine and trans out of the Mark VII I only grabbed the engine harness and the section of the interior harness that connects to the ECM. Then I found out that I needed more than what I had. That cost me 6 hours at a junkyard pulling out an interior harness.

Good to know if I decide on using the whole harness. Are you having your ECM flashed (tuned) or are you going to try to run it as is?
I'm still not sure what the advantage/disadvantage is of removing all the pollution control stuff?
I'd like to run the Trans, cruise control, turn signals, wipers etc off the original wiring as well as the cooling Fans and A/C.
Not sure if I'm going to try the ABS, power seats, power windows or fuel pump (not sure what to do about the fuel pump). Any suggestions???
Thanks for the help so far

I think you will need to flash the ECM at a minimum to get rid of the security stuff. I am eliminating the rear O2 sensors and EGR. I am planning on using the fan, AC and cruise control from the existing harness. The lighting, windows etc I will probably just use the hot from the fuse box. My understanding is the fuel pump has 2 speeds. I will be building a custom tank and utilizing the stock fuel pump. A buddy of mine is using an aftermarket harness and it requires that you use the stock pump. What year is your engine?

Mine is a 1997 SOHC out of a CROWN VIC. I was reviewing the wiring diagrams at it looks very similar to the DOHC. I may do another 53-56 F100 with the DOHC if I like how this works out.

I suggest that you purchase the complete wiring diagram for that car and work from it. You can get them on line for about $20.

Got a wiring diagram for the CV but I don't know what needs (can be) eliminated and what doesn't without adversely effecting its operation .

I have a truck with a '94 Mark VIII in it. I used the stock wiring. The best way to start is with a large wiring diagram like this one

I'll have to admit I was very intimidated when I first started. I just studied everything that needed to be wired for the engine and Trans and eliminated everything else. It started the first time and sounds great. I've since started a complete build on the truck so I've actually never driven it yet. Here's my thread, there may be something useful on there. http://www.ford-trucks.com/forums/10...its-alive.html


You can have your PCM reprogrammed to eliminate PATS. I also learned a lot on modularfords.com under 'MODULAR CONVERSIONS'. Very talented people on that forum as we'll. Good luck.

Shame on me. Just read your post, I saw part of your body work on previous posts but didn't realize you had installed the 4.6 DOHC. I usually pay more attention to the 53-56 stuff (cause I got em) but I've got to say GREAT JOB. That's one handsome labor of love

Thanks. Definitely a lot of labor. These old vehicles are worth it.
