I purchased this bike a while back and it didn't have a speedometer. So, I recently purchased a used stock speedometer/tach off of a 1999 Sportster with the wiring harnesses for the speed sensor and the connector in the headlight. I went to hook it up last night and found that the harness connector in the headlight didn't fit. I was told by a few people that it should work with no problems or i wouldn't have purchased it. When I look at the wiring diagrams, I only notice 1 wire (black/yellow) that is different in the connector.

So, my question is...
Will the speedometer work if i bypass the connector or rewire it? or being its off a newer model does it require something my 1996 model doesn't have?
