OIL PRESSURE GAUGE and SENDER
Model # GIOP, GIOP80, GIIOP80 All Colors
Installation Instructions
1. Disconnect battery cable.
2. When the sender has been installed it is automatically grounded to the
engine and the engine is usually grounded to the negative side of the
battery. If this is not true, proper ground connections should be made.
If necessary, a wire can be used for the ground path.
A GOOD GROUND IS IMPERATIVE
3. The gauge requires a 2 1/16" diameter hole in the instrument panel.
Install gauge making proper ground connection from the center terminal,
terminal " G ", of the gauge to battery ground.
CAUTION: Do not use the mounting post for a ground - use terminal " G ".
4. Use a good grade of primary ignition wire, well insulated and connect
the terminal post on the sender to the terminal post "S" on the gauge.
5. Connect a wire from the ignition switch to the terminal post "I" on the
gauge.
6. Connect light wire to shortest stud.
7. Reconnect battery cable.

STEP ONE(this usually solves the problem) - Before you do anything else, check
for defective wiring or grounds, as this is the most common cause of failures. Inspect
all wiring an terminals. Also, look for corroded or missing engine ground strap
connections.

STEP TWO - If pointer in receiver does not move when ignition switch is turned on,
check to see that current is actually being carried from the ignition switch to the
terminal ”I” on the receiver. Also, check to see that paint or corrosion does not
prevent proper ground. If pointer still does not move, receiver is defective and must
be replaced.
