  Install the three sensor harness wires along with the individual red,
orange and black wires into the orange insulation displacement connector
(see Fig.2 for positions), using the included wire insertion tool (R72023).
Follow the directions with the tool. DO NOT strip the wire ends, the
connector will pierce the wire insulation, and the insulation helps hold the
wire into the connector. Each wire must be pushed completely to the
bottom of its groove in the connector to ensure a good electrical
connection. Note that the 3 sensor harness wires run only between the
gauge and the sensor, not connecting to any other power or ground.
Connect the other end of each of the remaining wires as follows:
• Ignition – The red wire should be connected to one wire of the
included fuse holder using the included crimp splice, and the other
wire of the fuse holder connected to a circuit that switches on with
the key switch. Install the included 1 amp fuse in the fuse holder.
 Use only 1 amp fuses, higher amperage fuses may cause
damage to the gauge or to the vehicle.
• Dimmer – Connect the orange/black wire to the factory gauge
dimmer circuit by either tapping into the in-cab fuse block or by
connecting directly to the wire running from the dimmer on the
headlight switch.
• Ground – The black wire should connect to a clean ground on the
vehicle such as the battery negative terminal or a factory ground
bolt.

Slide the white dust cover over the orange connector once the wires are securely installed.
NOTE: The gauge backlighting will only illuminate if both the ignition supply AND the
backlighting circuits are on.
OPTIONAL: Daisy Chain Your Gauges – If multiple Performax EV 2 gauges are being installed in
one location (such as a pod), you may use a single set of the Ignition, Ground, and Dimmer wires to
connect all of the gauges. Simply pass the wires from one orange connector to the next one in a
“daisy chain” configuration. A single 1-amp fuse will protect up to 12 EV 2 gauges.

 Install the connector onto the back of the gauge (angled portion on
end of connector pointing up as shown in photo) , and then secure the
gauge in its mounting location. If drilling a mounting hole in a panel to
mount this gauge, the hole size should be 2.040”. Mounting Kit R19999 is
available for larger mounting holes up to 2.200”.
 NOTE!!! The orange connector MUST be installed in the direction shown. It is possible to force
it in backwards far enough to make an electrical connection which may damage the gauge!

 Secure all wiring so that it does not interfere with moving parts or chafe on sharp edges. This
may be accomplished by routing the wiring within the factory wire harness sheath, using wire ties
and sheathing, and using appropriate grommets when passing through the firewall.
