That diagram looks refreshing after working aircraft and automotive electrical...

 

Theres no way to know if they use the same color code on custom built bikes.

 

Yeah but the OP should be able at the most to figure out how to wire his bike from that diagram with any color wire he wants. The wire color doesnt have to match the digaram it screws the next guy but it gets the bike running. Id use correct guage wire though.

 

Bite the bullet and get a brand new reliable harness. For only 160 dollars you get everything new you will need and an instruction manual with labeled wiring. You will also get manufacturer support. Do it the cheap way and you will be chasing gremlins for life...either way you do it, remember that the integrity of the wiring connections you make will determine the reliability in the future. If you don't know what you are doing, get some help. Good luck!

Yeah would have been nice if it was in color though. Having worked Special Weapons as an Army Civilian, I learned the value of a good VOM and quality probes. I became the guy on our crew to troubleshoot electrical problems and got out of most of the dirty work while doing electrical stuff.

Had 2 years of electronics and 2 years of machine shop while in High School back in the day and that served me well over my working career. College would have been good but I was better as a trades person and working with my hands.

 

I did the trade thing also . I still have people asking me to fix their car and Ive been out of it for quite a few years.

 

He gone!
