Euro microswitch wiring

Does anyone with a Euro dino have a photo of the weber carb timing microswitch and its wiring? Note for those with American cars, it's different from the big switch on the cam cover of your cars.

I found the microswitch and its electrical terminal (tucked behind the fuel lines on front of the left-hand carburetor), but no idea how the wiring runs from there to the ignition plug in the trunk. If anyone has photos, I'd appreciate a look at them.

 

Switches to the second (R2) set of distributor points at idle for emission control. Unique to euro cars.

 

On the Dino the switch is on the left-most (clutch side) of the three carbs, facing the trunk, just behind the fuel lines. It has a spade terminal on it, to which is attached a wire that passes through to the ignition module wiring plug in the trunk. The female end of that plug has a corresponding wire that goes back out the trunk to the R2 terminal on the distributor. At least that's how I assume it's supposed to work. What I need are photos showing the wiring layout from the microswitch, across the engine, to the trunk. I've got a couple of photos of the R2 wiring, but none of the microswitch wiring.
