Which is which?

02 Ranger, 4.0L. I know there are two coolant/engine temperature sensors on this set up. One is for the gauge and one for the computer. They sit side by side and are both two wire sensors. One (on the left) has a gray connector and the other is a sort of orange-brown color.

Which one is for the computer?:icon_confused:
 
The one with a 4 prong should be for the computer. The two prong is for the dash gauge
 
Ok, I found on the explorer forum that the gray connector is for the PCM (hope that is right); but, now I find out there are two types. Screw in and push in!!!

Here is a picture of the sensor. Is it a push in or screw in type? Is that black ring like thing round the bottom of the sensor the clip? If so, how do I remove it. Thanks for any information, I don't want to tear into it and then not be able to put it back together.

 
That's a push in... You can see the retaining clip in the pic.
 
Definitely a push in that is held in by a retaining clip. I would recommend having a replacement clip for it before removing it since they tend to stretch and/or rust where you can't see it until it's too late and you are stuck until you can find one. Be careful removing the harness, not much clearance and you don't want to bend or break the pins off in the plug.
