[DeTomaso] Temp Gauge

[Dave McManus]

Good idea from Mike.

This information might save you some time:

The Borg-Warner WT324 or the AutoZone TS#58 should do the job.
 
The 260 degree gauge requires inline resistor,10 ohms 1/2 watt. The OEM
installation was in a plastic capsule Any electronics store will have the
resistor you need. You can clip the wire going to the sensor, slip some
shrink tubing on it, solder the resistor in series with the wire ends, and
then shrink the tubing to protect the resistor. (from SOBill Taylor)

Temperature sender fitting is 3/8 NPT male

Niehoff sender # TS-25621 from NAPA is equivalent to the Autozone TS 58

You could try a number of things; first and cheapest and easiest would be to
change the temp sender.   Order one for a 1972 Mustang with a water temp
GAUGE, not an idiot light.   That sender should be mounted on the front of
the
motor, NOT on the water tank (the tank is the stock, dumb location).

You can also wire a resistor in-line between the sender and gauge to knock
it
down some should that prove necessary, but I would be very careful to ensure
the accuracy of your readings before 'tricking' the gauge.

Where did you take your temp readings from?   Temps can vary widely between
the motor, water bottle, inlet side of the radiator, and outlet side of the
radiator....
