I bought a 94 Jeep wrangler. It was modified from a 2.5 to a 4.2L. The guy said he did not get the fuel, speedometer, or tach rewired. An MSD ignition box was installed. I started in yesterday trying to hook up these gauges. The original 2.5 L gauges are still there. The fuel gauge worked for a few minutes, then quit. I can't get the speedo or tach to work. Can anyone share simple thoughts on what I need to do? <img src="/forums/images/graemlins/frown.gif" alt="" />
