Hey chirrin

Welcome to FORDification.. the best Ford truck forum on the planet.
Thunderfoot is our resident electrical guru. You might wanna shoot him a PM.

It sounds to me like you have multiple problems going on.
If you have burnt wires, then you have a direct short somewhere.
Shorts that burn wires can cause numerous problems, wires with melted insulation can bridge and reak havoc on everything electrical.
If it were me, I'd search the wrecking yards for a complete harness that would match yours, or buy a new one from a good supplier like EZ Wire or Painless if you have the money...

what car did you get the harness off of? and did both the car and the truck have gauges or idiot lights? or did one have gauges and the other one idoit lights? that could be part of the charging problem.
