Alternator wiring

Quick question I can't seem to get a stwaight answer on. No both of the orang /black wires run into eachother on the alternator harness. I need to replace a harness and one wire either fell out or was pulled out of the connector and just taped up. And the new pigtail had 3 wires. Don't wsnt to fry anything. Any input would be great

Yes the two BK/O wires are tied together. They use two wires at the connector to split the current load between two connectors terminals.
This prevents the connector from overheating.
The third wire W/BK goes to the "S" terminal on the regulator.

I posted the stock 2G alternator that was original equipment for the 88 5.0.
If it doesn't match what you have, the alternator has been upgraded to a newer alternator.
If so give us a pic and or describe what you have.

Was this car originally a 2.3L Turbo Coupe? If so, they used a different alternator.

Would explain why the old pigtail is like half melted and soft to the touch.
