On the 86 Toyota truck 2.4 EFI how many wires go into the coolant temp sensor?It's to the right of the cold start injector switch and is green.

Sensors typically have only one wire going to them, the other part of the circuit being the the physical connection to ground.

There are several water temp sensors (for EFI, emissions, gauge), and IIRC one of the EFI has 2 wires but I can't remember which one.
