Power-Up
The pointer will move backward to the stop pin and then display actual temperature. This procedure is an auto-calibration function and is
performed on every power-up. While this test is being performed, the gauge may make a clicking sound. This is normal.

As a safety precaution, the +12V terminal of this product
should be fused before connecting to the +12V ignition
switch. We recommend using a 1 Amp, 3AG fast-acting type
cartridge fuse (Littlefuse® # 312 001 or an equivalent).

note: When the ignition is off the pointer may not always rest at zero.
note: Some late model vehicles use electronic sensors in their
pressure and temperature senders for engine control
functions. Before removing the original sender, we
recommend that you contact your automotive dealer to be
sure no critical functions will be disrupted.
1. Check that you have all parts required for installation,
and the engine is cool.
2. Disconnect the negative (-) battery cable.

4. Drill 1” diameter hole where wires pass through sheet metal
(such as firewall and install rubber grommet provided.
(Grommet will require slit.)
5 Connect the white wire to dash lighting or switchable +12v light
source, the red wire to switched +12V source and the black
wire to ground (see diagram for details)

B. Trans. Temp: Hole may have to be drilled, and adapter
nut welded or brazed in pan. Be sure there is adequate
internal clearance for nut and sender.
7. Cut end of included dielectric grease packet, and squeeze grease
into connector of temperature sender prior to connecting harness
(Important: This will protect connection from dirt and moisture.)
8. Connect red wire to switched +12V source and the black wire to
ground. (see diagram for details)
9. Reconnect negative (-) battery cable.
note: Test all fittings and connections for leaks. If any leaks are
detected, determine the cause of the leak and repair.
Do not operate vehicle if any leaks are detected.
