What is the best way to hook in a temp gage sender on the B7100 750D? I looked all over for extra port plugs, but had no luck, not even for oil. So I plan to hook the oil pressure sender into a T on the warning light sensor port. But what about the water temp? I would prefer not to compromise the tanks of the radiator. I could make a sleeve for the radiator hose, or maybe try to put a bung in the upper hose neck on top of the head. But I was hoping I missed a better way of tapping into the water jacket without actually having to add a tap into the water jacket...
