My 1992 oldskul L200 pickup seems quite normal as far as lights are concerned and also overall performance. It has already logged 350Tkms.

While I was cleaning the engine body I noticed that one wire...yellowish...was cut off. I traced it coming from the alternator. There were three wires supposed to come out of the alternator and only 2 wires are connected.

Since it was quite difficult to reattach the yellowish wire, I just left the situation alone inasmuch as the vehicle seems still normal.

I wonder where that yellowish wire is going. What could be the function of this wire?
