If headlight dimmer switch impacts dash lights , you have a miss wire or short between the red hi beam light and the dash illumination lights .
Or do you mean dash dimmer rheostat ?
While not sure of K all dash lights are orange wire on earlier 300 . Ought to be not too bad to look at each one , one wire must be feeding back . Miss wire or short to 12? Yes pull fuses one at a time find out if a circuit there is feeding back into dash lights . May or may not be one of those. Radio has 12 power and lights inside for instance . Probably clock too
