F 350 2WD Pickup V8-351 5.8L (1983)
Tachometer: Description and Operation
The tachometer is an electrically operated instrument which indicates engine speed in revolutions per minute (rpm). It is mounted in the instrument
cluster assembly.
The tachometer on F-150-F-350 and Bronco vehicles can be used with either 6 cylinder or 8 cylinder engines. The tachometer terminals "B" (+12 volts),
"C" (coil negative), and "G" (ground) are connected when used for 6 cylinder engines. A fourth terminal "8" (8 cyl. ground) is grounded through the
wire harness for 8 cylinder engine operation.
