Mopar1973Man

Hello. I was wondering if u had any ideas for me or something else to try. I've read your articles on wiring and No Bus and so on, but I'm striking out on everything. I have 1999 dodge Cummings 4x4 ext cab long bed auto and it's ppumped. I had a external waste gate on the exhaust manifold blow apart and melted the wiring harness. I've replaced the harness with a new one from a 99 Cummings auto truck. I had the PCM checked and it was fried so I got a remain for a 1999 cummins auto truck exactly like mine and the PCM works. Truck fires right up runs and drives besides being stuck in 3rd gear after this happened, no gauges work. I have all the codes 900-950. All the lights come on in the clusters air bag, wait to start and so on. Just the tach, oil, fuel, volts, mph does not work. Was hoping you could give me any ideas as to what to try or look at? Thanks for any help and thanks for all the great write ups u have posted! Andy
