So i got those big rectangle headlights on my 90 soverign now. But i also have a set of the rounds ones i got from pick a part. I know i could easily do the swap. its only like 6 nuts that hold the assembly in. but my question is abot the wiring. The round headlight low beam has different wiring. Instead of just 2 wires to be plugged into it, it needs 3. anyone know how i would need to splice it into the current wiring?
