I always wired those bikes from scratch myself eliminateing all the crap they don't need and greatly simplifying it. Everything still works I don't get rid of anything just don't put a few extras in. Plus the OEM harness on those bikes was below par to say the least. It isn't too hard to make it look OEM if thats what you want. The woven cloth sheathing is available to run the wire through. I have done it so many times now it's about a 2 hr job with no sheath.

I learned all I need to know about life by killing smart people and eating their brains.
