2006 W900 lights are haunted. Help!!!

[Grumpyjoewv]

Oh man I have a mess. The guy that owned the truck previously switched everything over to LED bulbs plus he added a few. He didn’t do a very good wiring job on the extra bulbs. The right turn indicator on the dash is lit when the headlights/marker lights are on. It’s off when the lights are off. If I turn my right turn signal or my 4 ways on with all other lights off, some of my dash/gauge lights blink with the flasher. I’m pulling what little bit of hair I have left out!
