Manual
Pressure gauges can measure the pressure present
in a system utilizing air or liquids. An electrical pressure
gauge is simpler and more versatile for installation
than a mechanical gauge but is not quite as fast to
respond to pressure changes. The factory warning
light sender can be retained to operate the warning
light with the use of a T-Fitting which is commonly
available at auto parts stores and is manufactured
by us.
NOTE: Some vehicles use electric cooling fans or
microprocessor engine controls that depend on readings
from the original equipment sending units for correct
operation. If your vehicle is one of these, then you CANNOT
change the OEM (original equipment manufacturer) sending
units(s). The only possible way to use non OEM sender is to
install it in a different location and leave the OEM sender in
its original location. Check with the vehicle’s manufacturer
or dealer to see if this is possible.

INSTALLATION INSTRUCTIONS
INSTALLATION
Gauge Installation
Make temporary test connection before permanently
mounting hardware or drilling holes.
This gauge can be mounted into any surface or into
a gauge pod. Refer to Figure 1.
1. Disconnect the battery ground cable before
performing any electrical work.
2. Choose a location to mount the gauge where
it will be viewable from a normal driving
position.
3. If you are installing the gauge into a surface (for
example the dashboard) make a 2-1/16” hole
for the gauge. Do not accidentally cut any wires
or hoses. Be sure there is clearance around the
hole for the gauge mounting bracket.
4. Connect the blue and white wires using either
Figure 2a or Figure 2b.

Do not install bracket and nuts until reaching step 8

For Electrical Gauges section.
PRECAUTIONS
1. Disconnect the battery ground cable before
performing any electrical work.
2 Route all wiring away from linkages, engine
parts that become hot, or moving parts.
3. Never smoke while working on your vehicle
It should be rated for gas/chemical/electrical
4. Never lay tools on top of the battery or wear
jewelry during electrical work to avoid severe
electrical shorts.
5. Locate and operate gauges so that driving
visibility is not compromised.
6. Check the owner’s or service manual, or your
local dealer, to be sure that the normal pressure
during cold-start and fully-warmed operation for
your engine or air system are within the gauge
range.
7. Be sure the tubing kit for the mechanical gauge
is long enough for your application.
8. Follow the instructions carefully. A leak that
goes unnoticed may lead to serious engine
damage.
9. Do not use sealing tapes or compounds on
electrical senders. This will disturb their ground-
ing connection to the engine/system, resulting
in false low readings.
10. Be careful not to crimp the tubing while unroll
-
ing it. Do not use any section of tubing with a
crimp or kink in it. If the nylon tubing is a little
awkward to use because of being rolled, heat
it in boiling water and let the tubing cool while
it is unrolled.
