good to see you girls working together.... have an 07 manual if you want to borrow Stix... or I could scan/email relevant bits
If you go to www.shareaproject.com and look up bikes and then go down to fitting a tacho on the streetbob it shows exactly where to wire into, here's the link to the page

Its an Alloy Art tacho mount, you can use whatever tacho you want, if you can get the mount, I have been sort of trying for several months without success, Alloy Art wont answer my emails, other outlets listed dont seem to have any either.
Thanks stix
