Before taping things up I did do a continuity check and got a hit on two points for the brown wire (remember it went one into two) - so, I was very confident I had solved the problem (and hope my other attempts had not damaged the speedo).

I used the pin to allow me to use my standard continuity tester.

Lots of tape, a few plastic ties, screwed everything back on under the tank, put the tank back on put those two screws, tossed the seat on and took it for a spin up the driveway.

First attempt (slow) no movement. Then I realized that silly little 10% thing, and went a bit faster. It works!
