What kind of bulb do you have?
You should be able to get the connector for it for super cheap just by asking around for it. I am sure someone will have an old harness or something where you could have them cut it off and send it to you. Thats what I would do before paying a shit ton of money for it.
If the bike is anything like my gix then the connector is very simple and #3 is probably a black rubber gasket that helps keep moisture out. Also might be found online in the classified section.
Glad to hear the fight went well. I was at a bar in Atlanta and people definitely went nuts when Matt kicked that dude. He seems like a genuine good guy too. Even more props for over coming his disability to fight.
I would really like to go to one of these fights some time but the tickets are always ridiculous and when I go to sporting events, I don't believe in being far away. Which means I would need big bucks, which is precisely why I haven't gone yet.
