I'm nearing the time to install the wiring harness from my 1990 Mustang 5.0 into my Maverick.

The EEC IV is for the AOD tranny - I'm using a C4.

I called Painless Wiring for a swap-out harness - $488.00

Did any of you guys go this route or did you simply modify an existing harness?

Any hints/comments/suggestions/photos would be appreciated.


If anyone has a schematic I could go by, I'd appreciate a copy of it very much!

Thanks in advance Guys - all I want is everything!

I haven't done this swap but I have been doing sort of low level research because I might do it in the future.

Here is what I have learned:

Most people prefer to use the stick computer (A9L) but the AOD one will work. I don't know the ramifications of unused sensors.

The cheapest source of wire harness is your local Pull-n-Save.

My plan is to use the Pull-n-Save wire harness and buy a wire schematic.

Please post your results, meanwhile we can both hope that someone with more direct experience helps us both out.

For those who plan to use an OEM harness on this type of swap, I have an 88 FoMoCo Mustang EVTM and I will scan pertinant pages and post or e-mail them as needed.

Hey Rick!

I think you can buy an installation guide with relevant wiring diagram info from Ford Motorsport and/or Painless seperately from the kit itself. You can always take Alex up on his offer, but a specific guide might be easier to follow.

Alex: Does the "88 FoMoCo Mustang EVTM" cover the SD to MAF conversion also? I assume if it doesn't I simply leave that wire. And 'yes', posting the pertinent schematic would be nice or if you'd rather, send via email.

Charlie: I forgot about the Ford Motor Sport wiring diagram/instructions. It's been so long since I've asked this question I forgot about them! Also, I'll email Painless also and post what they have to say.

I have the old harness from the '90 I'll be using. It is one he11 of a rat's nest and wieghs a ton!. I guessing 75% of the wires can be clipped.

Also, what about the location of the EEC? Mine was located in the PS kick panel of the Mustang. Where did you guys locate yours on the Mavs?

Thanks for all the input and suggestions,Guys. The more information we can all gather on the subject, the better for future installations/trouble-shooting existing conversions.

Keep 'em coming guys!

Thanks to everyone,

Rick

Information Overload on EECs:

Very thorough! (not exactly what I was looking for but this may come in handy for a lot of EEC guys)
