Making my EFI harness from an 89: What wires can I cut out?

[monk302]

Hey everyone,

I am making my wiring harness now out of an 89 EFI harness. I have my book by Charles Probst and have been reading it. What I would like to know is what sensors are absolutely necessary and which ones can I cut out. I would appreciate all your input and experience.

Not to give you a hard time. but do a search. Lots of good info just waiting. Then go to http://fordfuelinjection.com/ and read the whole site. Do use the power circut depicted there. If you still have questions come back & ask away. And post some photos of what ya got.

I just finished doing the same thing except mine was a 95 harness so it was slightly different.

Basically what you see on this diagram is all you need:

Somethings that aren't shown need to have resistors wired in to keep from getting a check engine light all the time.

Everything you need to know is over at www.fordfuelinjection.com

OOPS Tubo3 was posting as I was typing.

That kind of diagram is exactly what i was looking for. I didn't see that over on Ford Fuel Injection. Guess I didn't look carefully enough. I printed out a few pages of their instructions but didn't see that.

Additionally, Rustang, when you cleaned up your wiring did you just cut the wires or did you also take out the pins in the connector that goes to the computer?

I removed the pins and wires as a whole for a couple of reasons.

1) I am anal like that
2) I could put them back if I removed something I later found out I needed.
