I purchased a used soft ail and the previous owner installed an aftermarket headlight. I want to replace it with a "Bobber" style light but he performed a bad splice into the existing headlamp harness. Where can I find a replacement headlight harness that will plug directly into the existing harness and support high/low functions. I am OK with re-wiring it into the new light but I need an un-spliced harness that plugs in.
