Gary,
on closer look at the 2 pin sender VW 251 919 501 it does NOT appear to be the
CORRECT part for my Syncro. Its 2 pins are spades. On my Syncro the electrical
connector is a FI type coupling. I have asked Ron, at the Bus Depot, for the
correct part and I'll let you know what he sends.
Sorry for the misinformation,
Larry
