Wrenchbender Ret. or anyone else who can help, I'm bringing up my question again because I need to get more accurate temp readings. Question is, can I use a temp sensor for a gauge in the outlet on the passenger side head midway between the aft 2 cylinders and in line with the headers. There is currently a sensor of some sort in there that is not hooked up. I believe it is for a temp warning light. Thanks for any help, Don
