1. Disconnect the negative battery cable.
2. Install the oil pressure sensor. There are three common types of oil
pressure sensor installations:

Oil Gallery Test Port: Some engine oil galleries will have a
test port plug. Check your owner’s manual to verify the
location and thread size. Remove the port plug and install the
supplied pressure sensor. Additional adapters may be required
if the port is not threaded to 1/8
th -27 NPT.

Oil Filter Adapter Installation: You can purchase an Oil
Filter Sandwich Adapter from www.GlowShift.com. This
adapter installs between your oil filter and engine block,
providing you with 3 sensor ports in which you can install
the oil pressure sensor to.

T-Fitting Installation: Remove your stock oil pressure
sensor and fasten a T-fitting in its place. 1/8
th NPT T-Fittings
are available for purchase at www.GlowShift.com. Using a T-
fitting allows you to “T” off of the port and opens up 3 more,
which then allows for the stock and GlowShift sensors to be
installed and operate simultaneously.
3. Route the pressure sensor wire harness from the back of the gauge
(port D) through the firewall to the engine bay. Next, couple and secure
the sensor wire harness to the back of the oil pressure sensor.

Note: Be sure to use a grommet when routing wires through
the firewall to protect them from stripping and damage.
4. Connect the white wire to a positive 12 volt ignition (switched)
source. It may be connected to the fuse panel, an accessory wire, or any
positive 12 volt source that turns on and off with the ignition switch of
the vehicle.

Note: If wiring to an un-fused source, install a 3 amp fuse
inline within 20 inches of the sources connection. You may
obtain an optional “expandable circuit” accessory. This
component easily fits into your fuse panel and provides an
additional fused power wire for accessories such as gauges.
This is available at GlowShift.com or a local auto parts store.
5. Connect the
red wire to a positive 12 volt constant (un-switched) source,
either directly to the battery or to a fuse panel on the vehicle.

Note: If wiring to an un-fused source, install a 3 amp fuse inline
within 20 inches of the sources connection. You may obtain an
optional “expandable circuit” accessory. This component easily
fits into your fuse panel and provides an additional fused power
wire for accessories such as gauges. This is available at
GlowShift.com or a local auto parts store.
6. The Night Time Dimming feature decreases the brightness of the gauge
face by 30%. Connect the
orange wire to the 12 volt positive headlamp
source. This allows the mode to be activated when the headlights come on.
This step is optional and will not affect operation of the gauge if it is
omitted.

Note: Do not connect the orange wire to a dimmer wheel.
This will cause the gauge lighting to flicker.
7. Connect the black wire from the gauge, to any good (unpainted) ground
connection. You may also route a wire directly to the negative side of the
vehicle’s battery.
8. Reconnect the negative battery cable.
9. Daisy Chain Feature (Optional): If you are installing more than one
Elite 10 Color Gauge, you can use the daisy chain feature to power up to 4
additional gauges. Simply plug the included daisy chain wire into the
gauge that is already powered (port B); then plug the other end of the wire
into the daisy chain port on the next gauge.
