I have a 1977 CJ7 and my fuel and temp gauge didnt work. I found new gauges for 40 bucks shipped and replaced them. I put all the wires and the jumper bar back where it was when I took them off only to figure out that the jumper bar and the purple wire were both on the wrong post on the temp gauge and the jumper bar was on the same post as the red wire on the gas gauge. Today I put the wires and the jumper bar in the right locations but still no gauges, so could the gauges be fried due to the wires being switched around or should the new gauges be ok and I have a different issue with them not working?
