Does anyone know what these wires connect to? This is my only issue with the wire harness currently. I am used to vehicle wiring where everything has an identifiable and unique plug not just little pins that could go anywhere. 

Just an educated guess.
black with yellow tracer-negative ground

white with blue tracer-positive accessory connector(used if you want to add lights/phone charger..) 10 amp max

brown wire- positive wire to power lights for gauges, brake lights( check and see if all of your lights are functioning)

yellow with black tracer--not sure

Okay roger on all of that. The brown wire, does it connect to the gauges or what? The bike was laid on its side so I had to order a replacement gauge set and it’s not here yet so I’m unsure if there is a brown wire that will match it on the cluster. The only light that works is the rear running light right now. 

brown wire is 12 volt positive when key is turned to run

the brown wire connects to:
neutral light
oil pressure warning light
low fuel warning/brake light failure light
horn
front brake light switch
rear brake light switch
turn signals
The items are above ground switched. The brown wire supplies +12V and the switch supplies the ground through another wire.
reg/rec

The brown wire appears deep maroon on the schematic.

The ground switch makes sense, I was looking over the diagram and found that out. Thanks. I’ll have to see what all the brown goes to and what it doesn’t. Thanks!

Just finished the carb rebuild and top cover powder coat. Dang. Slicker than a minnows pecker.
