98 mazda b4000 where is the electronic body module & what does it do ???

I have had a diagnostic run & it does not show up!, you can't take just the gauge in its a cluster I know there is a switch & a sensor I was told usually the switch will cause this, I know where the sensor is but I do not know where the switch is ??????? Thanks for any help !!

I told you where it was. It's called the sender to the gauge.

I thank you for telling me what it is called but that still does not tell me where it is at!!

I mentioned it was at the right front of the engine. It goes to the gauge. The body control module uses the signal from the temp sensor but does not feed the gauge.

Thank You! I appreciate your help!!
