OIL

The oil pressure sender included with this system must be used. Other senders will

cause incorrect readings. If the sender mounting location is too small or is restricted, then pipe

fittings may be required to move the sender away from the restrictions. Oil pressure line may

also be used to remote mount the sender to the fire wall. The sender gets its electrical ground

connection to the engine block through its threads. Do not use Teflon tape or thread sealant on

the sender threads. Doing so can cause incorrect readings or cause the gauge to display an

out-of-range indication. If the sender is being remote mounted away from the engine, make

sure the sender case is ground well. The sender has 1/8 NPT thread size. If the engine you

have requires a different thread size you will need to use an adapter to convert the thread size.

Adapters can be found at your local auto parts dealer or hardware store.

A single wire should be run from the terminal on top of the oil sender to the control box

terminal marked OIL. If your wiring harness already has a wire routed through the vehicle for

the oil sender then it may be used. Do not route the oil sender wire along side a spark plug wire

or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge

readings. If the oil pressure drops below an adjustable warning point the reading will flash as a

low oil pressure warning. The default warning point is 10 psi.

If the oil display shows “—“ this indicates that the control box is sensing a short to ground

or out-of-range error from the sender or sender wire. If the oil display shows “EE” this indicates

that the control box is sensing an open circuit or out-of-range error from the sender. If either

indication remains on the display, inspect the sender wire for damage, check the routing of the

sender wire, check the sending unit grounding, and check that the correct sending unit is

connected.

FUEL

The fuel gauge sending unit is not normally supplied with the system. The display

system will usually use the fuel sending unit that is already in the tank. The sending units that

are compatible with this system are as follows: GM, Ford, VDO, and Stewart Warner. It is also

possible to program in a custom setting for senders that are not pre-programmed into the

system. The Stewart Warner sender type is used by most after-market gauges. A single wire

should be run from the fuel sender to the control box terminal marked FUEL. If your wiring

harness already has a wire routed through the vehicle for the fuel sender then it may be used. If

using a wire from an existing harness, make sure that the wire does not have power. The fuel

sender gets power from the control box only. Fuel senders get their ground from the sender

mounting plate. Make sure that a ground wire is connected from one of the sender mounting

bolts to the vehicle frame.

The fuel sender type is selected using the setup menu under “FUEL”. The settings are

discussed later in the section on internal adjustments. Anytime the fuel level is below 10% the

reading will flash as a warning of low fuel.

The fuel gauge will initially display “FL” until the fuel sender type has been set. If the fuel

display shows “—“ this indicates that the control box is sensing a short to ground or out-of-range

error from the sender or sender wire. If the fuel display shows “EE” this indicates that the

control box is sensing an open circuit or out-of-range error from the sender. If either indication

remains on the display, inspect the sender wire for damage, check the routing of the sender

wire, check the sending unit grounding, and check that the sender selection is set correctly for

the sending unit that is connected.
