CA RJM 3G harness

>>> you could have just use the 3G harness with your 4G alternator..... the harnesses are identical except the 4G one doesn't use the middle black/white ....not sure if it's the same now ,but my 4G harness from Ryan just has the black/wire sniped at the alt. plug...I imagine it's cheaper/easier for him to do one type harness then add the connector to the black/white wire for 3G use or snip off that wire for 4G use.........reason the black/white wire isn't needed on 4G alternators>>>-- the stator or "S" terminal wire which enables the voltage regulator to detect that the alternator is operating has been removed from the harness it is now connected directly to the rectifier assembly through a regulator mounting screw.......​
