MASS air conversion instructions from http://www.stangnet.com/tech/maf/massairconversion.html FREE
A9L (5 Speed) computer from junkyard $100-$150
A9P (Auto or in a pinch, 5 Speed) computer from junkyard $100-$150
70MM MAF from 94-95 Mustang GT - $40-$70
MASS Air wiring harness kit $30-$85

The whole thing is probably less than $300 using junkyard parts.

A9L computers are 5 speed only
A9P computers are automatic, but will work with a 5 speed.

I'm not sure which harness you melted/burned but whatever it is will need to be either repaired or replaced (obviously) because you're going to need it even when converting to mass air. They ain't cheap either. Here's once source you can look at:

the harness that melted is behind the engine along the fire wall basicly right were the MAP is mounted at least i think it's the map sensor little black box mounted on the fire wall behind entake

That would be the EEC-IV harness. If it's destroyed, you may as well get one that doesn't require a MAF conversion.

do you know what years would be a direct plug in

Call the company to be sure, but I'll go out on a limb and say that the harness they have there is MAF compliant (considering there's allot more of those in world than there are SD cars).

Just for reference, here's a list of all the compatible years:

89 harness should work for 86-89 as long as you're using mass air.
90 harness will only work in a 90. (B/c of air bags and dual dash connectors)
91 through early 92 harnesses should be compatible (single dash connector, fuel pump relay under driver's seat)
Late 92 through 93 harnesses should be compatible (single dash connector, fuel pump relay under the hood)

Computers from 89-92 are all the same. Look for the A9L sticker on the back cover for a 5 speed that matches your requirements. Example: E9ZF 12A650 AA" with the A9L code.
