So the newer Coyote has a full EFI harness & computer for $1500.
Does the '80's & early '90's SEFI have the same thing?
I can't find it with a Google search.
Everything just points to the normal full-harness swap.
Full of stuff I would never need/use.

I admit I have not searched as much as I should.
I only spent like 15 minutes.
But my keyboard is stoopid.
If ya'll can help by pointing me in the right direction, it would save me from typos and frustration.

I'm talking about full swap.
Engine & tranny & computer & harness.
And who gives a darn about emissions since my vehicle is too old.

Short answer..... no.

But the factory SEFI system is pretty simple and there are a few books that have the info needed to sort it out. The best bet is to transfer a functioning system from a Mustang to the truck. You can buy the various harnesses and add a used ECU or a PnP ECU and then tune it.

But nobody sells a complete kit that I am aware of. Pro-M is probably the closest with there stadn alone ECU system and wiring harness, but it still needs to be tuned.

The Coyote deal comes calibrated for what it is. Just like a factory car.

Look into Ron Francis wiring, they have a simplified harness for using the MS pnp ECU and i believe that had a harness for swapping 5.0 HO motors into other cars.

Wow. After all these years, I'd have assumed there was an all-in-one complete kit already available.

Thanks guys.
