It was on the floor of the car when I got it. It works, that's all that matters!

I am looking to convert from SD to Mass Air. Some local Mustang know-it-all said that not all FOX Mass Air ECU harnesses will work with the dash harness. That I need to watch that it has the correct connectors on it...

I don't remember the ECU harness hooking to the dash harness when I pulled it out, that was a while ago. Is there something about hooking to the fuel pump relay under the driver seat?

It's honestly been too long since I did my 88, but my FP Relay is under the driver's seat and I don't remember running anything to it. When I did mine, I just added the MAF wires to my existing harness and moved some of the wires in the harness to different pin locations. I found the instructions under the tech section on the Corral for backyard mass air conversion. Figured that was less of a PIA than changing the whole harness at the time.

you have to be careful when doing this? an 89 mass air harness will work in 87-89's.1990 and up are all different(I think).The plugs by the wiper motor are different especially cars with air bags and 93's only have one plug there
