1986 harness won't have the jumper to repin. The 1986 and 1987 cars are wired differently.
However, if the car's history is unknown, it's possible the wiring harnesses were changed.
Step #1. Look for the o2 harness plug near where the MAF would normally sit on a mass air car. Is it a 5-wire plug or a 7 wire plug with a jumper.
And yes, burning up trace 46 can cause some of the issues you are seeing. They can be repaired by soldering a jumper. Best way to check is to unplug the ECU, put a probe to pin 46 and check for voltage while cranking and on key on. Should be none
