Since your are in KY you are pretty close to this guy (a few hours but still lol)

Frank is a good guy and can probably hook you up with a new harness.

Alot of those issues can be cause by a bad multifunction switch (turn signal switch) but not all of them.

possible switch: ^
windshield wipers
lights only on bright
blinkers


fuel gauge - many possible issues....sending unit, gauge, wiring, slosh module, printed circuit board...
temp gauge- test gauge by grounding out the temp wire on the motor (single wire sensor on driver side of lower intake)
rear window defog - Does the light come on when you hit the switch?
fog lights- have you tested for power at the fog lights? Grounds?

cruise control
power mirrors - check for power at the switch and then check power at the mirrors when activating the switch

fuel door release- same as others check for power at switch and actuator

The plug that melted sounds like the ignition switch plug. Common issue.....



Remove the panels and start taking pictures of what you have and post and see if we can help. If they are just all cut up to be spliced into then matching wire colors works pretty well and butt connectors will work but soldering is the best way to go.

Im pretty sure the turn signal switch is bad the plugs that go into the flasher/ defog switch are broke half melted etc the idiot lights were removed for a toggle switch i have the cover and switches removed cause i had to jerry rig my headlights ill put some picts up here soon and the harness is gonna have to b replaced thanks for the help im highly knowlegable on everything about a fox body except the wiring im just glad i noticed the smoke and was able to unplug everything on side of the road

Well it sounds like you figured out your issues because they are visually obvious so replace them and get it done!

Well, you didn't state whether the car is a GT or LX, so...

If it's a GT, http://bit.ly/wBGz1y
