Ls swap and original chasis harness

[1968ls2fisher]

In the middle of swapping a ls2/t56 magnum into a 68 camaro. The camaro was restored about 10 years ago so it's in good shape. My question is the original electrical harness is connect to the starter, so after the swap I'm sure I'll reconnect to the new starter. But the front harness was connected to the alternator what do I do with those plugs. I believe there was two and a ground. Any info would be great. Pics or a diagram would be even better. If it matters I'm using Dakota gauges. Thanks.
