bunch o' problems
how do i tell if my pressure sensor is working or not?
second, where is the o2 sensor on the wiring harness for a 88 t2? i can seem to be able to find it. its is cut by the previous owner behind where the connectors are. cant seem to find a loose black wire anywhere to hook it up. does it suppose to go all the way to the other side of the engine bay?
third, under the tmic, where the tps and the sensor in the elbow, both connect into the harness, there's a black wire thats loose/cut, it doesnt seem to be connected to the eblow sensor or the tps. there's also a black wire with a connector right next to it and also cutted. the connector is clipped onto the tmic bottom bracket, does the two loose wires go together?

The o2 is in the exhaust passanger side the wire for that sensor is in the harness behind the filer neck on the top right side of the engine.The two black wires do not go together,One is for the o2 and the other I believe is for a sensor on the bac

setting the tps is used with the multimeter, its told to make sure to unplug the tps from the harness and set the key to on, what would happen if u didnt unplugg the tps form the harness and stuck the multimeter into tbe back of the plug? would it mess up anything?

That photo was just to show you where to look for your cut wire.

The knock sensor is used by the ECU to detect knocking/detonation/pre-ignition. If the ECU detects knocking it retards the timing to stop it. Being old technology, the FC's knock detection system isn't very effective over ~4000rpm, as the engine becomes to noisy. It's mainly there to avoid knocking caused by low-rpm lugging.
You don't need it for the engine to run, but it's a little extra insurance for free. All you have to do is connect it up. The knock sensor's wire comes out of the loom at the same place as the TPS and intake temp sensor wires.
