I’m wiring my 1964-66 Mustang after-market replacement parking light assemblies and the wire color codes on the after-market parking light assemblies do not match the American Autowire 510125 (AAW) 1964-66 Mustang classic update kit wire colors. What color wire on the replacement parking assemblies goes to which color AAW wire?

If you have purchased (shown below) replacement parking light assemblies for your 1964-66 Mustang, the after-market wire colors are Black and Light Blue on the double female connector and a Brown or Tan on the single male connector. To connect the after-market parking assemblies wires to an American Autowire 510125 1964-66 Classic update wiring kit, please follow these instructions:

Park Light

The “Black” park light wire on the after-market parking light assemblies will be connected to the AAW “Brown” park light (circuit 9A) wire on Circuit Branch 2. The AAW circuit 9A “Brown” park light wire is utilized to feed 12 volts to both after-market park light assemblies on the “low” filaments side of the 1157 bulbs.

Turn Signal

The “Light Blue” wire on the after-market parking light assemblies will be connected to the AAW circuit branch 2  “Light Blue” (circuit 14B) for left hand turn signal and the AAW circuit branch 2 “Dark Blue” (circuit 15B) for right hand turn signal. Both the AAW “Light Blue” and Dark Blue are used to feed 12 volts to the “high” filament on the 1157 bulbs.
