body control module

No, when it comes to modules (or any part of a wire harness) you want the part numbers to be exactly the same. There are likely differences between those two jeeps or those two years that make the BCMs incompatible.

Ok I have another question can these modules be programmed to work with different vehicles?

Some can be, but only to factory specs, and they're often not backwards compatible. Any place that has an interchange guide, like a salvage yard, might be able to tell you if they're interchangeable.
