Are Dodge Ram Kelsey Hayes ABS control modules interchangeable without programming?

My truck is a 1999 Dodge Ram 3500 with Kelsey Hayes AWAL (all wheel anti-lock) brakes. My ABS control module needs to be replaced. I've found several used units that are the same Kelsey Hayes model, but slightly different part numbers. None of the sellers know anything about interchangeability. Some are from Durangos, some from newer year Rams. Should these be interchangeable? Would I need to have the control module coded or programmed for my specific vehicle?

History: I have an ABS code for rear isloation solenoid short or open circuit. The AWAL (all wheel anti-lock) equipped Dodges have the rear isolation solenoid(s) integrated into the ABS control module, unlike RWAL (rear wheel...) which have the solenoid separate. I removed the control module and discovered one of the rear solenoids was badly rusted. The solenoids are soldered onto the circuit board. The board is glued to the aluminum case. So, solenoids aren't serviceable.

Hoping for a Dodge tech's help. Thanks!
