DO NOT Run wires from the tachometer loca-tion to a:a) +12 volt power terminal.(This positive power sourceMUST BE SWITCHED, andshould be protected with a fuse); Tachometer(3 " [80 mm] diameter)1 orProgrammable Tachometer(3 " [85 mm] diameter)1 orProgrammable Tachometer(4" [100 mm] Socket (Push in, wedge-type) Bulb (12-volt / #158 or equivalent) Spin-Lok Clamp or mounting Instructions1 Parts ListIf in doubt, please contact yourdealer or VDO Instruments at (800) : Read these instructionsthoroughly before making Installation .

4 Donot deviate from assembly or wiringinstructions. Always disconnect batteryground before making any : If you will use your tachometer withan alternator, you must first wire it (DiagramE) and calibrate it (Diagrams D & F) beforemounting it.
