What are these connectors? Buick Regal 97

[Pabz]

I took out the harness and forgot where these go help would be awesome cause i dont have a manual for this car.

the green connector is near the rear of the engine, the O2 sensor runs down that way.

 

The yellow connector is by the driverside engine mount near the air filter case.

 

This car has a 3800 L36

 

Here are some pics

what are the wire colors coming out of each plug?

 

yellow connector has red gray and black

green connector has org and black w/ white

[RobertISaar]

if the yellow one were gray, black and red/black, it would be for the A/C pressure sensor. i'm not finding anything else with that color combo in that location either....

 

the green LOOKS like the type used for the oil pressure switch, i've never seen that style used with anything else, that uses a tan/black and black/white wire set though.

green connector - oil pressure switch

yellow - coolant temp sensor

coolant temp should be yellow and black, if alldata is to be believed.
