Diagrams for what? Are you saying you need the factory wiring diagrams for the 90 LX or the wiring diagrams for a Coyote, or both?

The 1990 Ford Mustang wiring schematics can be found on eBay:

There’s also a shop manual with the vac & wiring diagrams:
https://www.ebay.com/itm/255038490496?hash=item3b617a8780:g:8qoAAOSwtGlZFNNl

1990-93 body wiring will be similar because of (2) factors:

- 1990 was the first year for the airbag system in a Mustang
- 1990 was the first year for MAF in the Mustang 5.0 (except in CA, where I think it was 1989 first year of MAF).
- IIRC, I believe the fuel pump relay was also in a different location starting in 1990, don’t hold me to it, but I do recall there being a change during model years.

For the Coyote set up, you’ll most likely need this:

Or something like this guide manual, which is what the Factory 5 Cobra Kit car builders use:

Thanks my friend. Wiring will be Holley. Need parts list like this pic but for entire car. But for my 90

You can try this, but you'd have to know areas or parts you're seeking to get a breakout diagram:
https://www.fordpartsgiant.com/

Then there is eBay for the actual 1990 Ford Shop Manual that will have many, many diagrams in them;
https://www.ebay.com/itm/195067757132?hash=item2d6af1c24c:g:s7UAAOSwfgZid~VG


The only other source of a parts breakout diagram like that would be the Mitchell Collision parts manual, but it's not Mustang specific, but is model year specific
https://www.ebay.com/itm/393047744118?hash=item5b83789e76:g:UEsAAOSwnclfztRh

The Mitchell guide will have the breakout diagrams similar to your pic, but not sure how deep you're looking for your project. I don't think it's as intricate as the actual 1990 Ford Mustang Shop Manual above.

What exactly are you seeking for the 90? Hard parts, soft parts, wiring?

One thing to mention too:
Ford Dealers will discontinue hard/soft parts after the 10th year of original vehicle production. So many parts for any 1979-1993 Fox Mustang today won't be found at any Ford Dealer, and possibly not even from those online. Your source for such parts will be eBay, salvage yards, and the specialty vendors like CJ Pony Parts, American Muscle, Late Model Restoration and National Parts Depot to name a few. You could also source said parts from online forums and social media outlets where those Mustangs are being parted.

Basically doing the car from zero. So lots of hards parts. Only difference is I already have an independent rear suspension for it and also a coyote 2 engine tranny. But need the entire body and interior
