Grounding Fire (almost) - Now What?

Smoked wiring.jpg

Car started acting up about a mile from home, thought I was losing my battery or alternator, but when I got it home and popped the hood, I see a 4 inch section of wiring is nothing but ashes. My guess is there was crack in the wiring casing that grounded out on the motor. Right below the gas line too - very lucky it did not torch the car.

Is the repair as simple as unwrap what is left - cut as much back as appears burnt, and build a new harness and splice it in? Best I can tell, the horn wires, the alternator wires, and the sending unit seen are the only wires in the bundle that burnt. Talk slow to me - electrical is greek to me.

For reference: 1967 Dart GT Convertible, 273 with aftermarket LD4B manifold.

Thank you in advance.
