I hope this helps and answers all of your questions. Please let me know if you have any further questions.
Very helpful indeed! This got me almost all the way there. However, there is no place on the existing power switch to plus in a "lock" set of wires (red/blue) from the controller. See the picture, uploaded. Any ideas where the juice to the lock should be plugged in on the machine? Or can I simply close the circuit on the Lock wire from the controller?

Upgrading a standard stock MX650 Razor Dirt Bike. Ordered a new SPD-481000B controller to upgrade the old one. The new controller isn't plug and play with the existing wires. Most of the set-up was straightforward, but I am down to the last bit and it isn't obvious how to proceed.
New controller: 4 plugs (labeled) with 9 wires (see image with four plugs)
Wires on the bike: 2 plugs with 8 wires (plugs not labeled; one with a red/black wire [think it is the brake] and one with six wires--brown, blue, yellow, white, black, and red)
Any suggestions for how to complete the wiring? I'm baffled by the different number of wires (9 on the new, 8 on the old).
Thanks a lot!
