Fuel – Yellow The fuel gauge sending unit is not normally supplied because the display
system can use the existing fuel level sending unit in the tank in most cases. If your wiring
harness already has a single wire routed through the vehicle for the fuel sender, then it
may be used. If using a wire from an external harness, make sure that the wire does not
have power. Fuel senders reference their ground from the sender mounting plate.
Connect the yellow wire to the factory sending unit. Be sure the toggle settings on the
switch match those displayed on the panel, as illustrated. NOTE: If the switch is on the
back of the circuit board the position is UPSIDE DOWN!
Both switches in the ON position for Ford/Chrysler
For GM - #1 toggle is ON
# 2 toggle is OFF.
Both switches in the OFF position for VDO
For Universal/Stewart Warner
#1 toggle is OFF
# 2 toggle is ON.
FUEL GAUGE TEST
The most common problem with our Fuel Gauge not working is the circuit is not complete.
The easiest way to test for this is to use a voltmeter and test for continuity on wires going
to fuel sender after disconnecting from gauge. If not disconnected it will give you a false
reading. With wire disconnected from Fuel Gauge check for continuity to ground. Then
test for OHMS to verify within range of fuel sender. If you don't have an accurate reading.
Run a new ground wire to engine without this the Gauge will not work properly. Note:
Verify Ohm range of sender and match settings before cutting a wire or setting Dip
switches for testing.
