I finished upgrading my aftermarket stereo by adding an amp to the aftermarket door speakers and another to a 7"JL subwoofer. Both amps were wired directly to the battery and groused to the frame. The power wire and ground wires used were similar gauge to my battery cable and inline fuses provided in the separate heavy duty amp wiring kits were used. The stereo wired great but initially I noticed that my dash lights did not work. I found a couple of 10 amp fuses out in the in-cabin fuse box (can't remember pin location) and replaced them. The light (dimmer) began to work but now I noticed that the whole gauge complex is nonfunctional, as is the little bogus "Trip Compiter". I checked all the fuses in the cabin and engine compartment and they are intact. I had done the zero pint calibration due to the veg and trac lights being on. Now nothing is on. Please help😓!

 

I checked all the grounds I could find and no wires seemed disconnected or loose. What would you do next, replace the instrument cluster? Replace the instrument panel computer?
