printrboard and vref?

All the pictures I could find for vref adjustment show the contacts you need to measure voltage on the old motherboard. Any pics anywhere for the new printrboard pointing out the correct place to measure? (I don't have to do this, mind you, but I'm just trying to gather info for the day I might :-).

I was also wondering if it might be possible to print a little widget that would sit around the pot and have a couple of points you could run wires around to make the appropriate contact and bring the signal out to a place where it is easy to clip voltmeter probes so you don't need 4 hands. This would have the additional benefit of masking off the area around the pot so you couldn't accidentally poke something with a screwdriver and regret it.
