Resolved! Someone had re-pinned the orange wire into the headlight connector upside down somehow. We now have dash lights and running lights.

This is the post creator’s brother. We discovered that someone had spliced a ground lead into the front indicator harness which was causing the fuse to blow. The problem I’m having now is power is simply finding a path to ground. The illumination pin on the dash has only 1-2 ohms of resistance to ground with the dash unplugged. The interior splice also has the same issue. We are also not getting power to the dash lights, wiper switch or anything else on the splice with the switch turned on.
Pull the LEDs out and start with incandescent bulbs. LED bulbs do not operate on two separate circuits (one for marker and one for blinker). They operate on one circuit with high and low settings which means an LED bulbs will cross your marking and blinker circuits at the socket across the circuit board in the bulb and cause a bleed over.
