the senders don't have "signals", they're pretty much resistors that affect the current flow thru the gauge, the "signal" is battery voltage to the power terminal of each gauge, the amount of power that the resistance allows to flow causes the gauge to read

I'd first off check the wires with an ohmmeter and insure things are connected to the right locations - next would be insure the gauges have power supplied to the proper terminal .... I'd expect to get a paper with the gauges that has wiring shown, and once wired properly, I'd expect the gauges to "twitch" somehow as soon as the key is turned, if not, they aren't getting power .... have a fuse panel?

Gauges are hooked uyp and has power, and are grounded. The fuel gauege is the only one that reads, the lights are also working in the gauge. They zero out when the power is off. The oil pressure gauge is not moving at all when fired up, but the computer is satisfied?? truck will run and drive just not sure if the readings are correct. that's why I was wondering if there was some type if signal I could check for?? I thought that was a simple enough question.I will call the harness maker and see if there is something I'm missing or he can help me with.Wiring has been rechecked grounds,hot,lights, etc... all seems to be in order.Fuses are good , gauges seem to be ok?
