He means the clocks plugged into the wiring harness. What did you have to do to install it? Retrace your steps from there.

unplug 3 pin connecter and plug de-restrictor into 3 pin block and bullet connector

Any other electrical issues?

Your problem is definitely with the 180km/h restrictor. Feed +12v to the orange/blue wire into the CDI and it will run right.

Black with brown stripe, try the brakelight feed, or there will be one at/near the CDI
