Help! Idiot light/Coolant sensor question

[poobut]

Does the idiot light have one or two wires. I think that my idiot light and coolant sensors are backwards. On the top of the intake on the drivers side there is a sensor with only one wire and just below the t-stat there is a sensor with two wires. Which is which? Also what is the ideal operating temp for everyday driver, mine is at 220? Thanks in advance

Idiot light/coolant sensor

Jerryl, I saw this picture before, but from reading some of the comments on the board it seemed that the idiot light had one wire and the coolant temp sensor had two. I removed the sensor below the t-stat, thinking it was the idiot light sensor, but it has two wires.

"Idiot light" switch has just one wire (on/off)
The 2 wire sensor is the "temp sensor" and required for proper operation.
