The middle pic is the plug for the back of the AC compressor,pressure switch I think.
The last pic of the two wires,is the purple wire goes to O2 sensor,and the green goes to the intake,for temp sensor.
I'm not sure which temp sensor but most connections on these cars will only plug into one thing.
Just don't plug the tach and fuel pump plugs together,they are just under drivers side valve coverand behind the ac compressor.
Hope that helps.
I'll head out to the shop tomarrow for the plug in the first pic

The Tach and Fuel pump leads that I described earlier don't plug into anything,they are test leads.
Sorry if I lead you to believe that they needed to be plugged in.
You can use the fuel pump test lead to drain your tank at the track,and you can use it to see if the pump works at all,Just make a fused jumper wire to go from the hot wire on the back of the Alt. to the test lead.

wrong
the fuel is primed by the A1 terminal of the ecm (grn/wht wire) when the key is turned on and its the only 'prime' and will only power the pump for a few seconds and requires the key to be turned off for approx ten seconds before it will prime agiain , once the ecm sees that the engine is running it will complete the a1 connection again and maintain it as long as the motor is running
thegrn/white wire goes to the relay on the passenger fender (relay with gray connector) .
there is a secondary backup incase the relay should fail and also to maintain power to the pump once started incase the relay should fail . its the oilsender switch at the front of the engine and will send power to the pump once the oil pressure reaches approx 4 psi , this is often removed for aftermarket sender and the car will still start and run as normal as long as the FP relay works properly.
the FP test terminal behind the alternator is spliced off the oilsender line so applying 12v to it by jumping it to the terminal at the rear of the alternator will make the pump run (even if you dont have a relay)
if you dont hve power at the FP/inj fuse you wont have a power source to run the pump since the prime and oilsender use that fuse ,
verify that you have 12v at that fuse when you turn the key on

heres another diagram
well, ya can say wrong or not, but the second single wire (not the green one) needs to be connected or you can sit there for hours trying to get the car started if there is no fuel pressure, it's not gonna happen. I can attest to this personally. Nothing at all happened till that connection was corrected.
