Yeah, that sure looks like a fox ecu conversion...
the white, black, and gray harness under the passenger seat is NOT factory...

If you trace that harness into the kickpanel, you may find an adapter plug going into the factory harness?

This is good progress, as now you KNOW what you are starting with.
Question is, how do you want to proceed from here?

What I would like to do is get the factory ecu setup back into the car, for 2 reasons. First, though there's probably nothing inherently wrong with the conversion, from what you guys say it now seems that the difficulties in dealing with the '94-'95 electronics have pretty much been overcome. If so, I don't want my car changed from stock for no good reason. The other reason is of course the fact that I have a pms unit for my stock electronics, not what is currently in the car.

I'm guessing that if I find a plug going into the factory harness behind the kick panel then I should be able to plug my factory computer right into that plug. That being the case, I should then also be able to plug the pms unit into that plug once I have anything else like the maf straightened out.

I don't know enough about the conversion kits to think I can help you get back to stock. Hopefully others will...

I suggest doing a Google search though to find out as much as you can on the conversion kit.
Try the following terms
PRo-M
PIH
Conversion

I think pro-m made the kit, but I'm not sure...

I have just yanked the kit out. It's a conversion harness, but the odd thing is that it has ford part numbers on the connector that mates to the original car harness. I bet that only means that the manufacturer of the aftermarket harness used a ford connector, not that the kit was actually made by ford. I think I'm now probably ready to reinstall the stock computer.

Edit: It is indeed a pro-m, and it looks like it might be worth a few hundred dollars. I'll hang on to it until I'm 100% sure I'm gonna be using the '94-'95 ecu.

The stock ecm is back in the car, and it runs better than it has since I've owned it. Driveability is great, though it's down on power especially at higher rpm. I can think of at least 2 reasons for it to be down on power, both of which will hopefully be fixed soon. The obvious one is that it's having to pull air through the dead supercharger. The other is that the maf is both in a non-stock housing and facing the wrong way. But, no check engine light and no bucking or surging at any rpm or throttle position.

Good job!

Keep us posted...

Thanks for all the help guys! Next I need to save up the money to get my blower rebuilt. Hopefully nothing went so wrong that it trashed the housing or anything like that. It'll cost $600 with the upgraded impeller, which I definitely want to get.
