 I didn't not answer your second part. I used a VDO T junction on the
head of the 1.6 Diesel and kept the old switch and the sender connected.
Never went back to the old pressure switch though so I don't think you
should do this, just unscrew the old and put in the new.

 I put the VDO dual terminal pressure sender on my 1.6L Gas type II and
my VW vanagon 1.6L diesel and it operated the light on the dash and the
guage and it worked great from 1991 to 2001 when I removed it as I
donated the van to charity - same sender, just transferred it (mine
guage was in bars and not PSI). I bought it from a VDO agent in South
Africa and I still have it at home somewhere. If you need me to look
arround for it and see if it has a part number on let me know.

Usually M10x1.0, try http://www.egauges.com/ for senders, etc.  Yes, I
run a dual output oil pressure sender, works great, one hole w/ two
funstions.  And you could probably try to hook up a resistance and power
supply to the meter and see what makes it read full scale.
