there seems to be 3 different diff lock switches for hte 7* series
and i seemed to have found one that says "Diff Lock" and all it points to is "off", no RR, no RR-FR
i have never seen this last one and was wondering what that is all about...
i checked the part number and my EPC is showing just a button and not a turn switch...
I spent over an hour the other night trying to find this part in the EDC too. The closest I could find was 83247D, DIFFLOCK ASSY, but it showed up for PZJ7#..STD during 9108-9208 and it certainly doesn't look like a switch; yet the fork and other locking diff parts were available for more models and dates. I was pretty confused.
