TOPIC: Smiths electronic speedometer installation

After 5,6 ? speedometer drives, the last one went tits-up 10 miles into the ride to the rally last year, I decided to go with the Smiths electronic. It is made in Wales, all the parts, I am told. The tripmeter and odometer toggle, but you have to wire in your own switch, none on the instrument. ( WTF).
I mounted the magnetic bolt on the rear disc and the pick-up on the caliper plate, It probably won't be noticed. The instrument mounts in the origional cup, looks great. I will be mounting a toggle switch next. Then I will be wiring everything with 18 gage wire. When that is done I will have to ride with a GPS and calibrate it.

what is the additional function of the switch that is not a single 12v ignition power on/off??? 18ga? why so fat?

The additional switch is a toggle switch will change the odometer to the trip meter. 18 ga easier for me to work with.

OK, I get it a ladder type programing using a single open/close switch.to navigate the programing rungs...

Wiring complete, all connections soldered and sealed. I installed a toggle button on the dash, to change from odometer to trip.Next is good weather (warm), ride it with a GPS to calibrate it. Just to make it more interesting, one of the (9) wires coming out of the speedometer was a different color than any of the ones shown in the instructions.

Pickup is mounted on the Rear Caliper Mounting Plate, the magnetic nut is on the disc
