Quick question for 3VZ-FE owners, which sensor is the coolant temp sensor?

I see two sensors side by side, is it the left one or the right one? My Haynes manual doesn't say exactly, but I'm thinking its the one on the right.

anyone?

Now I see three possible candidates this is confusing!! I want to do the potentiometer mod, and the Haynes manual mentions 2 ECT sensors!!! which one is it!?

Can some knowledgeable person tell me which one it is?

the one with 1 pin is the sending unit for the guage

the one with 2 pins is the temp sensor

I'm not familiar with the 3VZ-FE engine, but the engine coolant temp sensors usually have a green colored plastic connector going to them, in most cars I have worked on.
