[Vwdiesel] VDO oil press senders

Any experts on the list regarding VDO oil pressure senders?

I just bought a VDO electric O/P gauge off Ebay - it was listed as being for 
Ford/Chevy (?) so I assume this means it uses the "US" Ohm range as per 
e-gauges.com. The part # shown on the box (it hasn't arrived yet) does not 
match anything I can find, so I assume it is old stock. 

1. Is there a quick way to verify the "ohm" range or is it usually marked on 
the gauge?
2. What is the thread size for the cyl head pressure sensor (and the oil 
filter flange sensor - they are the same I think)?
3. Has anyone tried the dual output senders, which are designed to trigger 
the oil light on most vehicles? They don't say what the trigger pressure is 
for these switches. 
My only experience is with mechanical pressure gauges, and I've always 
just removed the cyl head pressure switch and stuck the mech line on 
there. This will be for my Vanagon diesel (stock 1.6 for now), so I'm not 
sure I want to remove the stock pressure switch.
