wiring up my light

The front light should have wires coming from the switch that go to it. Should be a yellow for low, green for high and black for ground
 
THere isnt a switch mounted on the left side of the bar for on/off and lights? maybe someone who had the bike before you took it off . i think u are gonna have to look at the wiring harness and find the leads.
 
ya i see in ur pick u have a teather switch where the on off should be. not a big deal. u will ahve to find some missing wire that might have got chopped!
