Generally the auxillary air regulator is 3/4 to fully open when cold, and when warm all you can see is that little vertical slit.

JBL's advice is right on. But I believe you need to have the engine running before you'll be able to measure any voltage at the WUR connection. Just turning on the ignition won't put any voltage there.
