Ground connection on gas engines
On gas engines, the control unit ground and engine ground should be connected to
the same electrical ground point. Otherwise, the various components of the system
may detect different potential, which leads to interference.
The term control unit ground refers to pins 2 and 5 in the C4001 harness-to-harness
connector. See also C4001: Harness-to-harness connector for engine control unit
.
Engine ground refers to the ground screw on the starter motor.
