see my post in this thread from july 15
http://www.gz250bike.com/viewtopic.php?t=420 it was about 57 dollars delivered. Sometime soon I'll write up a "how to" with pics. It was easier to than I thought it would be. Took me about 1.5 hrs. most of that was figuring out where to mount, connect and route wires. I'd say it could be done in a half hour or less. When I find time I'll write up a "how to", prolly this weekend, I took plenty of pictures.
