I would need someone with a TII to confirm this, but I think its the plug for the knock sensor. Every 89-91 n/a I have ever seen has one unused plug inthe wiring harness. Same plug as the O2 sensor, right? I think the TII's and n/a's use the same engine wiring harness. The n/a ECU just doesnt have a pin for that wire.
