how about a nice, pre-wired switched circuit box WITH good instructions for the B400. Something like an Eastern Beaver PC8 but include the correct length wires and drilling, mounting and wiring instructions. This seems like the E-ticket solution for anyone who wnats to take the next steps in adding eceltical options like heated grips or clothing, lights, etc.
