Recently I tried to install a radio in my truck. The unit didn't fit in the dash slot so I abandoned the task. The next time I turned on my truck, none of the gauges worked. No gas gauge, no tach, no temp, no voltage, etc. Only the Speedometer works. I checked the fuses and couldn't find any that were burned out. I have been driving it without them for a little while and I feel it's time to figure out what's up. All of my other electrical stuff works with the exception of the 4 wheel drive, which has manual hubs and electrical on/off. Any help would be great.

Did you touch/cut any wires from the existing radio-you might want to check the ignition switch power to the radio could be shorting out and causing the gauges to react-

I did not cut or cross any thing. I just plugged it in found out it didn't fit the dash slot, then took it out and tossed it behind the seat. Next day my dash didn't work. The radio did not turn on when I had it plugged in though.

I got some repair manuals from the library and I looked up my problem, and it says it is a faulty Instrument Voltage Regulator, but it doesn't say where it is or how to replace it. Where would I find this thing?
