I’ve searched many places here and elsewhere and I cannot find a coolant sensor block that looks like mine (1988 3VZE 4Runner).

My best guess is it’s the one on the far right of the three, but does anyone know definitively which one is the ect sensor?

The 88 and 93 fsm’s show it on the left. But maybe the diagram is reversed.Someone else said it was close to the radiator??
