I purchased a new aftermarket dual headlight for my 2004 Softail Standard FXST to try to adapt it to more of a fat bob look. Once I got it, I realized that it wasn't the same kind of wiring harness as the original light. The bike has the old-school 4-pin clip-in plug, but the new headlamp has a 3 prong plug as well as 2 loose wires that appear to be grounds or something. Is there a way to rewire the headlight into a 4-pin plug or do I need to get some kind of conversion kit? If so, where do I find such a thing or how can I make it? Thanks for any advice.
