No check engine on the rubicon although without lockers, the switches no longer work of course. We used the old locker switch location to put in a light bar switch so nobody thought so try to use lockers that weren’t there. The 4wd indicator didn’t swap across with the tcase swap. I don’t recall if the plug was different or it may have broke when we did it (we didn’t care so didn’t try to make it work - I’m guessing not that big of a deal). The two tcases use different shift linkage as well. I don’t recall what the options were but we just put savvy cable shifters on. Depending on gearing, you’ll probably need to adjust the Speedo as well.
