It is a separate sender for the gauge. It is very small and threads into
the lower metal half of the thermostat housing. It is difficult to see
from the engine compartment. You need to lie on your back under the
driver's side cylinder head area. The housing bolts to the front of the
head, front being front of the car. The gauge sender is 1 wire, the Temp
II uses 2 wires and is nearby. The same single wire sender is used on
millions of other VWs from the early/middle 80s so they cost little and
are easy to find. This info does not all apply to 2wd Vanagons, only
Syncros.

>My temperature gauge quit working and I am trying to figure out where it gets the signal from.  I always thought that there was a temperature sender and the Temp Sensor II was a separate temperature sensor for the fuel injection.  Does the Temp Sensor II also send the signal for the dash temperature gauge?
