Hey I'm swapping my 74 Nova front bumper, grille, headlight bezels and eye brows to the 72 Nova style. I've completed the entire swap and just trying to figure out the wiring for the turn signals. The 74 has a 3 wire (brown, blue and black) and the 72 is a 2 wire (brown and blue). I want to retain the park lamp function. Anyone completed this swap and have any intel they can offer. Electrical and wiring is not my strong suite haha so any info would be great.
