I believe the dual terminal sender has the low pressure switch set at .5
bar.  This will make your oil light flicker at idle (BTDT).  It is best
to get a single terminal pressure switch and use your existing sender
for the oil light.  I just bought one of the single terminal one from
Egauges.com, but they are also available elsewhere.

Egauges.com has some information on their site regarding compatibility.
They are not all compatible.

Subject: Somewhat ignorant oil pressure switch question..

The VDO dual-terminal sender, such as
http://busdepot.com/details.jsp?partnumber=360006
Does it only work properly with the corresponding VDO gauge? ie will
some
other FLAPS gauge work??
