Alright so since I was confused about the tps adjustment, here goes round 2.

There are 5 different colored circles here. Stop me if I am wrong.

Red: The actual throttle position sensor

Orange: the 3 pronged connector where I must ground one terminal and check resistance at another terminal once my engine is warm (88 SE Non Turbo)

Green: Is this the adjustment screw for the TPS? Something about getting resistance to about 1k Ohms?

Yellow: One of a few diagnostic connectors hanging out around my engine bay. I was hoping someone could tell me what these were actually. Or if they are of any use.

Blue: Another set of connectors that were unplugged when I bought the car. I plugged them on but did not notice any difference in drivability. I was wondering if anyone knew what these were for if there are any reasons they might be unplugged.

In particular for the blue circle I am referencing the blue and off white connector that are sitting side by side.
