There was a flash fire near the carbs and the original wiring harness was damaged beyond repair in the fire. The rest of the bike is still good and that is why I am rebuilding it. I found another wiring harness on Ebay for 35 dollars but I have heard good things about the simplicity of the M button and the junction box and switches. But, the price tag for it all is a good $400 dollars. That seems a little steep but it does seem like it makes things easier to wire back together. Another piece of my situation to consider, I am looking to swap out the original headlight for a dual LED headlight (two lights side by side that still fit in the original headlight cradle) so I won't have all the wiring space behind the original headlight like it used to.
