It seems kind of interesting, I have the same indicator on my 1980 CJ5 (EMGCY DRIVE). Except that it comes on whenever the dash lights are on, as though it were part of that circuit. On the other hand, I just took apart the multi-gauge from my 1980 parts CJ5 and that position says 4-WHEEL DRIVE. I'm not surprised that the wiring for mine is messed up, it's just the next in a long line of issues I've had. Great info John and lucdog, thanks. Now I've got something to do while I wait for fuel gauge parts to arrive.
