ISX15 to x15 2012 Pete

[DirtyKarl95]

What all is needed go from an ISX15 to an x15 on a 2012 Pete? ISX15 is a cm2250 and the x15 is a cm 2450. I am looking for a solution to re pin the truck to ecm harness. I see they sell a kustom harness just trying to avoid the 2 month wait on the harness. We start harvesting corn next Monday.

ISX15 left the dealership after an oil change and locked up 5 miles down the road. Someone put 10wt hydraulic in it….
