since i had a water temp guage laying around i got a wild hair to put it on my new ranger. so i got it all hooked up and ready to go backlight works guage needle even moves up and is ready to go. so i got to looking and found the sender for the stock guage and the 2 fittings autometer gave me were either 2 small or 2 big. so i decided i would try to connect it to the stock sender thinking it would work. tried both wires nothing works?????????????? should i e-mail autometer and ask them if they make the sender for my car or is there some trick u guys know? should be that diff from a mustang.
