Anybody Using A Promracing Efi Harness In A 1991

[Scoot5.0]

I really would like to find a new ECU to engine harness for my 1991 Fox. But it looks like nobody has a stock harness available. I need to keep cali emissions working. I found this Promracing EFI harness and computer. Just wondering if anybody else out there has used this and have passed cali smog. Check this video. Installing the Pro-M EFI Harness

I don't think it'll work. The eec end of the harness fits the pro m eec which is different than the fox eec.

Right, the Pro m supplies a complete system, stand alone computer, wiring harness, the only thing they did not do was certify for CARB, as there is no provisions for the EGR, Thermactor (air pump), and the purge canister, I trying to find people in California that has used this and has passed smog test.

I think late model resto has fox body reproduction harnesses. Look for the corral.net forum discount if you choose that route.

What's wrong with the one that you have?
Does the engine run?
Is the Check Engine Light on?
Are you getting any codes?
