Alternator Wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an alternator from a 1998 S10. Looks like it is a CS130D (according to Rock Auto). At the time I picked up the alternator I also took the alternator connector. It is a four pin connector with only one wire in it (which is in the L position on the connector). When I look up a connector for this alternator on Rock Auto (1998 S10) it shows only one wire.

All of the wiring diagrams I can find for a CS130 alternator show two wires. Do I just use the one wire and do I need a resistor in that one wire (or will the idiot light for charging provide the resistance)?

Thanks.

Wade
