No skim bus message? What do I do now?

2000 cherokee 4.0

had to replace the computer because the case was broken. Got one from a reputible salvage yard. Popped it in, starts fine but dies after 3 seconds. Scanned the computer I get a P1686 "No SKIM bus message"

OK that makes perfect sense. I have no SKIM key, so there is nothing to read. I check at the dealer. Service guy tells me Cherokees never came with SKIM in 00, just Grands. Hmmm.

I Go home and decode the VIN that came with computer. 2000 cherokee 4.0. Call up the yard, explained it all to them, Sure we will take it back, just ship it to us at your cost and expect a 25% restocking fee. Great!

so here are the questions.
-Am I in the correct ballpark here diagnosing the problem?
-Is there anyway around the SKIM?
-Did cherokees in fact not have a SKIM?
-Can the dealer flash this computer so it works for me?
-If cherokees do in fact come with SKIM, how do I tell that when buying another computer?
