Let's make this the official wiring diagram thread... Please add them as you find them.. If you have a specific electrical or wiring question about your bike, please start your own thread. Thanks. Here are some wiring diagrams I found on the net. Some of the file names give a clue as to what year or model they are for. Tip: To see some of these at full size, you may have to click on them once or twice after they load depending on the internet browser you are using and your monitor resolution. Credit to www.xs400.net for the colored one.
