How would I go about wiring in a break light into my current handle? Is it as simple as splicing a wire that is already going to the controller?
it's rarely that easy, but there's a number of ways, depending on your system's wiring, voltages, and the type of ebrake lever you have (if you have one), and the light you want to use.
so...do you have an ebrake lever?
if so, what type is it? some are two wire, and just have a switch in them. some are three wire, and have a hall sensor like the ones in your motor (not like the one in your throttle).
is the switch open unless you pull it, and then closes to complete the circuit when you pull it? that's the most common type. or does it do the opposite?
what kind of light do you want to use? common 12v led type? or incandescent? or something higher voltage?
fwiw, teklektik's yuba mundo 2wd cargo bike thread has a load of good wiring and setup info for turn signals, brake lights, etc., including parts lists and links, wiring diagrams, etc.
my sb cruiser thread has some info but no wire diagrams (maybe someday...if there's ever time
), and the info is scattered throughout the thread.
