Installation Instructions
Plug each probe into its associated Extension Cable. Be sure the connectors mate properly. When tie
wrapping these cables down, be sure there is no strain or pull on the cable against the probe or connectors.
Dress each cable up to the instrument keeping them away from any hot areas such as exhaust stacks, cylinder
heads, etc.
Tie off any excess cable under the instrument panel. Be sure these cables do not obstruct the freedom of
travel of any controls.

Connect the red wire in the Connecting Wire Harness to the 12 or 24 volt bus via a 1 amp fuse or circuit
breaker (see the Wiring Diagram at the back of this manual). Connect the black wire to ground. Connect the
white/brown to the 12V bus (leave it open for a 24V system). Connect the white/red wire to the 24V bus
(connect it to ground for a 12V system). Connect the white/orange wire to the Panel Light Rheostat.
Tie off any excess cable under the instrument panel. Be sure these cables do not obstruct the freedom of
travel of any controls.
