My buddy just did a swap, he put a '93 Mustang engine into his '90 Bronco, both 5.0's. The Mustang engine went in complete, but with the Bronco upper intake. Has the Bronco wiring harness, still. Here's the thing. I got it timed, it was a little too advanced, but it still runs rough...and there's no MAF or harness for one that we can find. Anyone know where to look? I took a look at all his parts, there's nothing that looks remotely like a MAF unit that I'm familiar with, and all the Bronco forums are geared to 4x4's and 5.0 to 5.8 swaps. He has a Chiltons for the Bronco, but it says disconnect the air tube, and there's nothing there...TIA, I know this doesn't fit here, but it's worth a try.
