I'm new to the forum so any help would be greatly apprieciated. I installed a new set of isspro ev2 gauges in my truck last week. I have the pyro, boost, and rail pressure. The boost gauge is the middle gauge of the three. All three gauges light up when the ignition is turned on. The pyro and rail pressure both cycle as they should as well as function. My problem is, the boost gauge does nothing after this? Shows no needle movement while driving. Lights still work. They dim as they should, but nothing as far as function? My boost sensor is installed into a GDP air horn and all wiring is covered by wire loom. The hot wire is tapped into the ignition and the illumination is tapped into the light switch dimmer wire. Everything works great except the boost gauge? I have checked and re-checked the wire connections to the connector. They are seated. Anyone with any ideas please feel free! :banghead: Thanks
