Installation: Easy as 1-2-3
  1. Find a convnient mounting location, be sure the pick-up wire will reach the spark plug wire. If not, substitute with a wire of the same outside diameter of no less than 22 guage, up to 8 feet long. DO NOT mount meter where surface temperature exceeds 125°F. As a general guideline, if you can place your hand on the mounting surface without discomfort while equipment is at full operating temperature, then it will be suitable to mount meter in that location.
  2. Use drill template (Fig 1) to locate mounting holes. DO NOT DRILL INTO GASTANKS OR ENGINE CRANKCASE; if in doubt contact your dealer.
  3. Secure pick-up wire into meter by placing wire over channel and pushing down with a flat screwdriver. Wire must be seated cimpletely in channel (Fig 2). Fasten meter to mounting surface with supplied screws. Route wire to spark plug wire and attach as show in Figure 3.
