I mixed my 2 temp sensors up and don't remember which one went where. I have one with a light grey plug and one with a black plug and they have different pin layouts. One went in the water pump and one in the drivers cylinder head. Which one goes where?

 

grey one goes in the head

 

I'll confirm 1eyedmaro by saying my original WP sensor has a black plug.

 

Confirmed x3. The one in the driver side head also has a "stepped" probe.

 

2 terminal sensor goes in the water pump. 1 terminal sensor goes in the head.

 

Good deal. Thanks.
