Alternator connection

Ok so I'm a bit confused about hooking up the alternator on my swap. I went the carb'd route, so just dealing with the original harness.

I have a 4 pin alternator on the 6.0. I purchased a Holley 4 pin alternator pigtail, because it was advertised among my Amazon purchases, and the reviews said it was helpful with an LS swap. Sold. Anyways, I'm really not sure what wires from the harness to hook up to the pigtail? The old SBC alternator was externally regulated, and has a 2 wire plug into the alternator. I'm not sure if anymore info is needed.

Re: Alternator connection

I noticed that for Holley's alternator instructions, this is noted, might be the same for yours;

"When wiring the alternator, connect the “L” terminal labeled on the alternator to switched voltage that is “on” when the key is in the run position. There must be either a charge indicator light (standard dash bulb) or a 560 ohm, 1/2 watt resistor (Radio Shack #271-1116) in-line on this wire. Holley’s part # 197-400 already has the resistor in line."
