alright so correct me if im wrong, cause but White is constant,y-g is switch and black and yellow ground??
Uh, if you think B/Y is ground you probably shouldn't be messing with this stuff.
B/Y is ignition (IG) switched 12 volts for powering the IC regulator which in turn controls the field winding.
Y/G is the warning lamp (L). Unlike many older cars failure of the lamp in this system will not result in a lack of charging.
W is the sense (S) line. It tells the regulator what the voltage is at the battery so the system can charge it more accurately.
B is the big wire back to the battery (B). The alternator output.
The pinout for the connector is on the next page...
