So you got ya new flash front end and no Speedo. Splash some cash buy new fancy unit (dangerous word on this site:D), now you are to run cable down fork leg and glue magnet in brake disc, Or attach to rear brake hanger to count bolt heads and as it gets hot readings go a little off.

A lot of units need 5 v feed so little drawing old skool style showing how to use a more industrial sensor found on machines which has 12 feed in with ground and trigger wire return of 12 volt which then reduced to 5 volt via resitors to keep your nice new posh electricy whizzy thing happy.

I drilled out bandit sprocket cover sensor and drilled output shaft which needs to be done on lathe to bolt trigger plate onto end of shaft. But there many ways to do this it's the leccy bit I'm showing in this how to.
