So Ive been under the impression that i could use an engine harness out of an 89 to convert my 86 to mass air. I was talking about this with the guys from MPS and they said it wouldnt work. Anybody done this? Will it work or not?

I don't see why it wouldn't work. The last year without airbags is an 89. It's a lot easier to convert your existing harness to MAF though.

I believe you have to swap out some connectors on the harness

Ive got a conversion harness, but some of the wires in my existing engine harness were chewed up by rats when the car was sitting. Is the wiring for the coil in the engine harness or headlight harness? Because thats mainly the area where the rats made their nest.

It is in the computer wiring harness.

See http://slantnosefox.com/picturehosting/jeremy/86 electrical & vacuum troubleshooting manual.zip you can download the whole set of electrical troubleshooting and diagrams for an 86 Mustang courtesy of Jeremy, AKA V8only.
It is a big 61 MB download that you get to unzip and save on your computer. It may take some time to download it, but the results are worth your time.
