One works for pressure, but I am wondering what the other is for.  Didn't seem to work with my temp gauge.  Does it drive the idiot light?  Just joined the list, have been reading the archives for a few months.  I have just finished a diesel scirocco conversion and it runs like dirt.  Won't idle, no power, lots of smoke, all the good stuff.  It was a russian roulette engine transfer.  I am just happy it works at all.  It sits now patiently awaiting the diagnostic fun to begin.  Can't wait!

Its likely for an idiot light.  My VDO oil pressure sender has two
terminals, one is an analog resistance that drives a pressure guage, the
other is on/off for the low oil pressure light.
