Even when I turn the truck of lights are on. Lights on mirrors, id lights lights next to signal lights. I'm thinking there's a short somewhere. Any insight appreciated. Insite fault viewer shows 23: instrument cluster #1 also 167: instrument cluster #2 faults

Not far ago someone posted link to Prostar electrical circuit documents. I would start from here and check LCM signals.
