EFI conversion wiring

I re-wired a 1989 EFI harness for use in my 67 Mustang and recorded all the steps and made diagrams. Anyone interested?

did you write down all the ones you could cut off ?

i put a 90 harness in my 73 240z and its a 4 wire hookup.. power- ground- fuel pump - key on power..

what i didnt do was keep track of all the ones i cut off and deleted..


there are lots of sites that show what to hook up.. havent seen specific with colors of what you can remove for 89 and again same for 91 fox.. (they are different efi harness)

This site is helpful if your wiring up your own EFI setup. I've used it a lot when i got my motor wired up.

Thank you Robert!

Robert, thank you for making this available. A tremendous amount of work and very generous of you to share your experience!

Dirty Harry is a 1967 Mustang Convertible, 289 2v, automatic, soon to be 331 with Kenne Bell 2.2 Flowzilla Blowzilla, AODE. Next project is my Arizona 1966 Fastback...way down the line!

Some of my favorite phrases, and yes, they're mine.
People make time for the things they want to do, and for everything else, they make excuses.
Wisdom is mother nature's substitute for intelligence.
Is it really bad luck, or poor planning?
Do something, or say nothing.
