Connect the red, orange and black wires to the orange connector as described above, in positions 1,
2, and 3 respectively. 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.
 The lighting harness is designed to be used with Performax EV²™ gauges. DO NOT
attempt to use this harness and potentiometer with any other gauge types.
 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.
6  Install the connector onto the back of the gauge (angled portion on end of connector pointing
up as in Figure 1), 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”.
7  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.
