anyone have a good source for these gauges

www.egauges.com sells lots of different makes and manufacturer's

gauges

for

auto applications.

Also, can anyone tell me what the sensor is on the back of the water

pump

housing?  I have 1986 13B and this sensor obviously has something to

do

with

water temperature or pressure - it has 2 flat metal plugs for a

connection.

I know that the water temperature sender is way in the back of the

engine

under the oil temperature/pressure sender.  So what's the thing on

the

water

pump???

Thanx,

Possibly the temp sensor for the supplemental ac condenser electric fan
equipped 2nd gen rx7s. Also all the third gens (that had only an
electric dual fan set up) had a similar sensor, turns on at 226F and
another temp sensor for the emc computer as well. 3 sensors in all on
the FD water pump housings-I think.
