Wiring Diagrams (and insight?)

[krsowles]

Hello all, Noob here! I’m looking for wiring diagrams for 2008 RAM 1500 with 5.7. I have a “no bus” with the possessed dash and no speedo along with intermittent no start. I have checked all grounds I have found, some crusty and cleaned/ reattached. I have pulled TIPM and all wires from and found no corrosion. I have done the same with PCM (also tried a replacement from Flashmasters which didn’t change anything, so old PCM reinstalled) and removed instrument cluster and saw no visual defects. I need to start checking wiring, hence the diagrams. Wire checking may be beyond my capabilities but with a YouTube University degree, I’d like to at least try. If someone knows of wiring diagrams or assistance, that would be great. I do know my head is spinning from all the reading I’ve been doing
