Basic instructions (edited somewhat):

Remove the whole wiring harness. Have some ring connectors and female spade connectors on-hand. You'll also want wire cutters, and crimpers for the connectors.

Dissect the harness by pulling the wires out of all the tubing (re-use tubing as well) and lay it all out. Follow this to get it running and later clean up all the “too long” length of wires:

yellow wire from statorrun to headlight and ground headlight nearby (brown wire)
green wire from statorrun up to one brake light switch and blue/green back to junction block and blue/green wire from stop light
gray wire from statorgray of taillight (make sure taillight is grounded)
green blackground to frame
blue/blackground to frame
blue wire from statormeets blue from coil and coil should already be grounded

Put another short blue wire into same terminal as blue coil wire. use this and touch to anything metal to kill the bike. Later you can run this wire to a kill switch and ground the switch.
