Found a bad buttsplice under the fuse box in the engine compartment thank you gentleman

Iv checked every fuse in the motor compartment. Also the ones in the cab. There's no power in the box at all. I pulled the harness from inside the cab went thru it cleaned it up. When I start the pick up my instrument panel also acts up. Oil pressure pegs out fuel go to empty. Double check all plugs to make sure they were all plugged in. I'm at a loss now. Can't find a short any where. This also has no power to it. It seems to click about 30 seconds after the key is on Also my fuel shut off solenoid disengaged running down the road that's when things started to unfold. I'm trying to put as much info as possible. The box under the hood has power

It's a 94 5.9 cummins. It did happen as soon as i pulled the light switch out

The other night installed a manual temp gauge and was under the dash running the line to the motor. I bumped somthing or somthing happened. I seen my lights flicker on my radio. I then pulled my head light switch out and bam absolutely nothing works. No power at all in my fuse box. Wiring diagrams would be a big help. The harness are shortly to say the keast
