1. Gauge connects to 240-33 ohm fuel sender (3262), supplied in Quad
gauge/Speedometer kit. Sender is not included in individual Quad
gauges. The 3262 or comparable 240-33 ohm sender will be required.
Route proper length of 18 gauge wire from fuel tank to gauge. Connect
one end to terminal post on fuel level sender and the opposite end to the
spade terminal labeled “FUEL” on back of gauge. See illustration.

grommet. Attach one end to the negative GND (-)
spade terminal on back of gauge, and the opposite
end to a good engine ground. See illustration at right.
2. Attach one length of wire to the positive +12V spade
terminal on back of gauge and opposite end to +12V
terminal on ignition switch or other switched +12V
power source.

CAUTION!
As a safety precaution the Red wire of this product
should be fused before connecting it to the positive
(+) side of the 12V DC battery. We recommend
using a 4 Amp, 3AG fast-acting type cartridge fuse
(Littlefuse

# 312 004 or an equivalent) inline with
the Red wire of our product.

NOTE: Some late model vehicles use electronic sensors in their
pressure and temperature senders for engine control func-
tions. Before removing the original sender, we recommend
that you contact your automotive dealer to be sure no
critical functions will be disrupted. With pressure gauges
it is beneficial to add a T-fitting to install your new gauge
and to keep the warning light operational. This allows you
to monitor the pressure and still have a warning light to
indicate emergency conditions. The ground, fuel sender,
temperature sender, and oil sender wires should be routed
through fire wall using the supplied grommet.

NOTE: Hook up of the voltmeter powers the quad gauge. Not
hooking up these wires will result in the other gauges not
working.
NOTE: The Quad gauge will not operate with any other resistance
range and cannot be modified to do so
