In 86 you they used either a 10si or 12si alt. regardless they are both wired and function the same, the terminal can go to the battery, on the plug you will find a red 10ga wire (located to your right ,holding tab up and the plug facing away from you) this wire can be hooked directly to the battery aswell. The other wire usually white 16/18 ga, is your voltage sensing wire and is hooked up through your ignition switch it then goes through a combination of a light and usually a resistor wired in parllel (used as a failsafe in case the light fails).This wire is used to excite the field to close the circuit turning the light off and start charging , with out the sensing wire with a light (as resistance) you end up with a hunk of copper and metal that does nothing.

I assume your talking about the rectangular plug right at the alternator, and that your new Alt came with a short repair harness, the 2 heavy wires are BAT and the slim and likely white one is Tachometer AC sense, likely that 3 of the old ones were Bat test the old connector with a test light to see which of them have power to them.

Detach the negative terminal from your battery, detach the wires from the alternator, detach the drivebelt by loosening the pivot bolts and the adjusting screw for the alternator and then slipping it off. fully loosen the bolts and the others that are holding the alternator to the engine, they are fairly easy to find and then go to buy a new one. Wherever you go to purchase a new one BRING YOUR OLD ALTERNATOR WITH YOU. You will need to visually compare them to make certain they are EXACTLY THE SAME. the parts number should be printed on a label on your alternator, make CERTAIn that it is THE SAME as the number on your new alternator.
