I had to combine the AOD’s reverse light/neutral safety switch harness with the same from the Mach 1’s original wiring harness. I also decided instead of using crimp connectors, to solder and ‘shrink the connections between the AOD harness and Mach 1 harness. Much stronger and longer lasting splices.

Here’s the “hybrid” AOD/Mach 1 reverse lights/neutral safety switch harness, all cleaned up, spliced, and loomed.
