I have a 98' Mustang GT with the 4 speed automatic trans with overdrive (4r70w). My wiring harness got burnt up pretty bad from touching the exhaust so I repaired it and then the same thing happened. I am just going to replace the whole harness for the tranny. This guy on facebook marketplace has a 4r70w for a 99-01 ford explorer. Will the harness from the explorer work in my mustang or does it have to be specific to my mustang and if so where could I get one at, I already checked rockauto, partsgeek and a couple other auto websites like that. My wire harness has 8 plugs, two of them being for downstream o2 sensors and the another two going the plug in's inside my engine bay and the other 4 to my transmission itself. I can provide pictures of my harness if nessecary.

No, it will be very significantly different from an Explorer harness. Even a 1999-04 Mustang will have a slightly different harness. Your harness is likely only used from 1996-98. You will not find a new replacement harness for your car. Only Ford made them and they're long out of production.
You need to fix the basic problem as to what's causing your harness to touch the exhaust. That's not supposed to happen.
