I was not suggesting buying the whole panel...although you can. I have found them on eBay for around $500. Seaboard sells the for around $1200 like you said. If those are OEM Cummins then you have an OEM Cummins engine harness. It would truly allow to "plug and play" if you bought the entire panel.
The only reason I know all this is because I am currently redoing my entire engine panels. Carver butchered the original engine harness to put in their own instruments and not Cummins/VDO. I Spent $2000 alone in just gauges and wire and senders. Labor is likely to be just as much. I am rewiring the entire panel as well so sire has to pulled from the engine room to the flybridge.
