Hello vettevet. Can you explain? If he installed an LSx engine, and the pcm is doing the regulators job, why is he connecting all that stuff to L terminal and S terminal? I guess the original gauge cluster needs the S and L terminal, right? The LSx pcm, harness, and alternator should work without the external regulator. I don't want debate, I want this info for future reference. I do a lot of wiring and I don't recall doing it this way but you may be smarter than me. I don't qualify as the sharpest to tool in the shed.
