84lx 351 efi conversion

[ryan7662]

Don't know if this was alreday covered in another thread but I sure could use some help if anyone can enlighten me. I have a 84lx that I just put a rebuilt 351 and wct-5 manual tranny in. It originally had a cfi3.8 v-6 in it with a a/t. I also have a red 95 gt that I'm using for donor parts since it'll be rebuilt into a drag car eventually. I already have a efi lower and figure that the 95 f250 distributor and ignition control module will fit the 95's harness. I can do a complete transplant from headlight to tailight if necessary but if you guys know a easier way i would very much appreciate it. Thanks guys for any info you can share

And I will be using the brackets and timing cover from the 95's 5.0. I'm confused about how to wire up or bypass the emergency fuel shut off in the trunk(it looks like it goes through my 95"s main chassis harness) and where the power distribution block for the interior(underneath the steering wheel) gets its power from. For the life of me I never found a main power distribution block in the engine compartment of the 84 like my 95 had on the driver side next to the battery. I searched high and low but couldn't find one leaving me to assume it was wired wrong to begin with since it always had electrical problems. Thanks again guys

The 95 Mustang used a CCM module that is not present in the 84 Mustang.

See http://infotrac.galegroup.com/itweb/sava66375?db=CHLL&id=40539003520151 for wiring diagrams

You will need this harness
Ford Racing M-12071-A50 - Ford Racing Multiport EFI Wiring Harness Systems – SummitRacing.com.
The harness only works with the TFI module mounted on the distributor. Make sure your distributor has the TFI module mounted on the side and uses a gray TFI module.

You will need an A9L or A9P computer

You will need an after market MAF to match your injectors. See http://www.massairsystems.com/ for a unit that matches your needs.

I appreciate it man but I was trying to say I have everything needed to completely wire the 84 as a 95 would be. I have a complete 95 gt donor car and can pull anything off it that I need even if means rewiring the 84 with the 95's wiring from bumper to bumper. I'm doing this because the 95 wouldn't pass emmisions with the 351w and I just like how my 84lx looks better than my 95 gt. I was just wondering if there was a way to transplant the 95's computer,sensors and all necessary electrical parts without having to also use the 95's interior wiring, instruemnent cluster and head/tailight wiring.

oops

My 95's engine split in half after running too much boost on it so when I do eventually get it running again it'll be a drag car so I'll probably be rewiring it anyway so it won't be missing its wiring harnesses even if I have to completely take out all of its wiring. I have its ccm and everything that it originally had nothings missing its' engine is just cracked in the main webbing are thats all

And since money has become a issue I want to use the electrical equipment from my 95gt even it means painfully working from bumper to bumper transferring the wiring from my 95gt to my 84lx. I'm just wonderig if there are any shortcuts or places I could tie the 84's chassis harness into the 95. If not I do have plenty of time to do a complete eloectrical transplant between the the two cars. Sorry if it sounds like I'm ranting but I just won't to make my situation clear to you guys. Thanks again for any input on this cause as crazy as it sounds I can't turn up anything on yahoo or google
