Hey guys can anyone please help me? I'm almost done with my LS swap but am stuck atm trying to figure out how to wire the alternator. The 5.3 alt that I have has 3 wires in the plug. One is pink w/ blk tracer, the next is a light brown or tan, and the third is black w/ white tracer. The pink/blk wire is in the P spot. The brown wire is in the L spot and the blk/white wire is in the S spot. The old engine was a 4.3 and only had 2 wires. Do I even need all 3 now? Any help is greatly appreciated.
