I am just starting my first cafe (xs400) project and I want to do a home brewed harness, I just want to run a head/tail light, a snazzy allman? electroinic all-in-one speedo, and I just want my batt, to stay charged, I pulled my stock harness, and I have a ignition unit, do I have to wire this in, or can I just wire up my reg/rectifier in a simple system, I have been living on your site as of late, newby. I have not found any other posts that can help me with my basic wire job, if anyone can help, that would be awsome, p.s. have factory manual but it makes me cross eyed :-\
