im pretty comfortable with automotive wiring, and GM wiring in particular, I hope this is a easy issue. GM 12SI alternators with a charge light have key on power to one side of the 194 bulb (a pink wire, usually fused on the gauges fuse) the other side of the bulb is connected to pin “2” of the alternator on a brown wire. The bulb technically isn’t required, a 35ohm resister could also be used. So how are the truck with gauges and no warning light wired? Is there a resistance wire inline with the brown charge wire? I have cut apart 2 truck harnesses, unless I’m looking right at it I’m not finding a resistance wire. What am I missing?
