Was taking out aftermarket radio to put in a dash kit to help keep it stable. Realized the previous owner didn't use butt connectors for the wiring. Unplugged the harness. Installed dash kit, plugged harness back in. Connected battery and went to start the truck, the tachometer, speedometer, radio, gear range, and odo did not turn on. I have a hunch it's cuz of the crap wiring they did but I'm not 100%. Would appreciate tips, ideas, or input. Thanks

 

Start by checking fuses. Might have popped one in the process by letting a loose wire touch another one or ground.
