Hi Phatman, I am guessing your riding a 82 xs400? I know my 81 XS400, the safety/relay are under the battery tray, forward of the middle bar/right under it. somewhere on this site is the wire diagram for the 82 bike, and knowing what colors wires are going to which relay will tell you what type of relay your looking at. I am working on my bike, and after figuring out what I gotten, I have quickly marked it with a silver permanent marker. so i dont have to figure it out again. as far as bypassing it, probably not the thing to do with out the diagram. My bike the Safety is wired to the neutral switch, and a power wire is router though there for a reason, that alot of us have surmised. But its more thinking than I am willing to worry about. today anyways.
goodluck Tobie
