Some partially melted wire harness connectors on top of the engine. No obvious separations. Need to know which wire [ harness segment, color] to start inspection for mil.[ no mil, p0650] small fire under plastic engine cover about 100 miles ago. Runs good, but I'm weak in electrical issues.

The P0650 trouble code is a generic powertrain code that indicates a malfunction in the "Malfunction Indicator Lamp (MIL) Control Circuit."
