In my 86 n/a had an antenna cell phone installed in most likely the 90s when they were a thing and I went ahead and removed it today, which included ripping out all the the cables and wires for the phone one of which wires I followed down the door and along the door sill on the passenger side and to a black box just sitting under the carpet in the passenger footwell. From that black box there was a plug that had 3 wires connected to it the ran up behind the radio and ac controls in the center console then down the other side of the trans tunnel somehow ending up on the drivers side fuse box where there were 2 wires tapped into a fuse in the first column toward the bottom and another tapped into a fuse in the second column also near the bottom. So from there I removed the wires from the fuse box and pulled the wires through the center console and under the carpet from the other side until they pulled out In doing so I somehow messed up my digital dash because it was fully working before however now it is not displaying anything at all and the power supply is 100% good.

any tips at all or suggestions would be ver very appreciated since this is my only car and without the dash working it not only is annoying but the car has almost no value now.
