Finally had a few minutes to install my gauge cluster (water temp, voltage, and oil pressure) in my 1968 Firebird. They are simple mechanical Bosch gauges. Temp needle never moved. Sucks. The instructions state to never kink the temp probe cable ensuring there’s always at least a 3 inch curve/loop/bend. Laughable!! It was wound into a tight (2 inch by 2 1/2 inch) wad for packaging. There must be an approved wrap that won’t hurt the cable. Jegs customer service won’t answer the phone. Fine. Can’t find a number for Bosch. Frustrated. I love doing things over and over and over…..
