Question : Coolant temp Sensor vs. Coolant Temp Switch

[Lockman]

Hi ..... The Sensor has to have coolant circulating around it, in order to do it's job. I Must install A Mechanical Temp sensor & Gauge. How do I ? Can I tee off of the Switch or the Other Sensor ? Or, which one could I eliminate with out bothering the ECM ?

The one on the front passenger side of the intake manifold. It only controls the idiot light. The top drivers side is the overheat fan switch and the front drivers side tells the ecm engine temp.

You can replace the temp idiot light switch with the temperature sensor. It's located on the front right area of the intake manifold. It has a single wire on it. I see you mentioned a mechanical temp sensor. I would go with an electric one. Easier to install and you can use the existing wire on the original temp switch for the electric gauge. Much easier.
