Putting UIM back on, a few connectors that I forgot where they go!
Gentlemen, forgive me, but it's been about 5 months since I first removed my UIM and there's just a few connectors that I either can't locate mates to or am overlooking. I spent some time with my Haynes manual, but have not had success. Car is an 88 TII 10ae.
The green connector is knock sensor? When I first pulled the harness I'm fairly certain this was not connected. Single pin connector not sure of at all. The white 2 and 3 pin connectors at the top should go to the two connections here I believe:
These guys both are 2 pin connectors, so I definitely don't want to get them mixed up! The Bn/Y Bk/W connector is about 6 inches longer.
Finally, there are 2 connectors that utilize a Bosch injector style clip. One is the BAC; is the BAC the one wrapped with the injectors or is it the one that is loose?
Thank you very much for your assistance. If in addition to the component name you know a general area to search for it I would greatly appreciate it.

Top pic: (Left to right) IAT sensor connector, TPS connector, and (considering this connector is all the way on this side of the engine bay...) knock sensor connector. (The lower green connector is a check connector. No hook-up.)
Second pic: On the compression tube is the two prong IAT sensor. The connector that is also in that photo is obviously the TPS connector. (You are correct about them being associated with the above connectors.)
Last pic: (Left to right) Air bypass solenoid valve. The white connector with the B/W wire up top and W/B wire on bottom is for your alternator.
The Bosch EV1 style connectors you are referring to... The blue one is for the BACV. The green one is for the water thermo sensor on the back side of the water pump housing.

The Bosch EV1 style connectors you are referring to... Yes, the blue on is for the BACV. The green one is for the water thermo sensor on the back side of the waterpump housing.
I will be editing this. (Looking for the two connectors I hadn't mentioned.)

Also, both EV1 connectors are green plugs and appear to have green wires in them, I did not see blue. The second white connector pictures is actually Lt Gn/Bk, not W/Bk (hard to tell from lighting).

Ah, okay... That wire did look like the White/Black wire associated with the alternator. It goes to the air supply valve connector then.
About the EV1 connectors... The connector with the wires L/G and B/W is for the BACV. The connector with wires B and G/W is for the water thermo sensor.
(The BACV is blue and the water thermo sensor is green. That is why I always thought they were matched with the same color EV1 style connector. Guess not...)
