I've deal working on this for 9 months now.
I never listed the final product here on FSB because I never thought anyone would be interested. But it seems I was wrong.

Special introductory price of $375 untill October 3rd!

Expected to look like this:

Prototype looked like this:

I'll have a picture of a completed harness by the end of the week

The bass harness will be wired for:
5.0L or 5.8L / auto or manual trans
88-93 Mass Air Mustang computer
Intake facing the passanger side
Fits both long tube headers and shorties.

But I can accommodate ANY custom request. It’s a one piece harness design; fewer connections make for less future failures.
Will actually plug into a stock 66-77 Bronco or Mustang body harness along firewall.

I have got a rough draft of the istallation manual on line:
http://fordfuelinjection.com/manual.html

Harness specs:
Brand new 260*F+ OEM Ford connectors, not reproductions.
265*F Bosch relay block
265*F Buss fuse block
255*F GXL wire
1200*F Fiberglass loom on O2 sensor plugs
300*F Corrugated wire loom on rest of harness
Wrapped in OEM harness wrap

I dare anyone to find a better harness. This harness
will be top dog in a market that charges $400-$1000.
We are only charging $375 and must have all money collected by Friday October 3rd.

man, i really want that, my 302 harness that i am using with my 351 is like going to self destruct, plus the IAB hookup is too short so i had to splice a little bit more wire onto it (like 6 inches) which could be the casue of why that valve is not closing on warm idle.

ill see if i can scavanger up some money. i have been wanting some fancy new wire underhood! or maybe ill just wait untill i get serious about trying to swap the the mustange MAF. well we will see.

Stoked check your PM box

Hey Fireguy...I wanted to say congrats for getting this deal done. Props to you for having the vision and the fortitude to stick to it. I hope its tremendously successful for ya.

I'll find out tomorow and friday when it's time to collect from the investors and pay the factory :banghead
Stressful times are ahead

Mr. Fireguy, What exactly do I have to change on my wiring harness for the 351 swap?

Ryan -> :twak <- Tim

Uh, nothing but hole! LOL change the computer and engine.
If you want mass air, ship me your curent harness while the engine is out.
It will return to your re-born

check your PM box

Isnt there something that has to be fixed for the bank to bank/sequential thing?

can't be "fixed"
fact is you must add 10 wires to the harness and move a dozen others, add a relay or 2, ect.

Wow I make it sound easy LOL :lolup

I am not talking Mass air right now, just getting the 351 to run right..

Oh, well like I said :twak
change engine, change computer, leave harness alone.

Both 302, 351, & 460 truck computers fire injectors:
1, 4, 5, 8 togeather
2, 3, 6, 7 togeather

Firing order, cam, engine, none of it changes the injector firing.

You gona trust me on this Tim? You gota! :beer

Dosent that waste gas?

I trust ya, just making sure my questions are clear...:beer

No, the gas waisted by that method is only a few gallons over 20 years. I too can't really grasp how it doesn't waist more, but it's like a electric carb. Carb's can't not pump fuel into an intake runner or direct fuel at any one cylinder.
Drag race engines are ran the same way, they aren't looking to save a few gallons in the long run, and it's easier and chaper to program a comptuer to run 2 sets of injectors

Do mustangs fire them seperate?

yep, 1 at a time it's called "sequential firing injectors". truck group firing is called "bank firing injectors"
