Ok, I probably already know the answer to my question, but want to ask any way. Rode with my guys today to pick up new police bikes three hours away at the HD shop. While I was there decided to get a siren for my personal alarm system. Told the guy what I had, he looked it up and gave me the Smart Siren II, which is what I wanted, but he gave me a 68328-06, after I got home and looked it up myself, book says I need a 68317-06. I have a 2000 Ele. Glide Ultra classic. Can I use the one he gave me or will I need to drive three more hours (actually six) to return it?
