Or zip tie them or of the way and forget about them??

The top one looks like the windshield washer fluid level sensor connector. I don't think it was used on the MJs. The 88 electrical manual can be downloaded here http://comancheclub.com/topic/12083-electrical-manual/?fromsearch=1 if it still works.

That link is just what I needed!! Thank you immensely!!  And you are correct on the unused windshield washer plug, the other is the Power Steering sensor plug, which also is not needed.

You can add a w/s reservoir from the equivalent XJ application that has the level sensor to your MJ and plug in it.  Add a bulb to the appropriate socket in the indicator panel to the left of the instruments, and you are good to go!

What's the up arrow?

[Marine1Texas]

arrow up means shift to a higher gear....

[cruiser54]

Upshift indicator light on manual trans models. Supposedly, if shifted then it would meet EPA fuel mileage estimates.

The up shift light is my overdrive off light on my V8 powered MJ.

I stuck in the 97+ washer tank inside the left fender well, and the washer fluid level indicator definitely comes in handy. The bulb was already there on the cluster.

What's the up arrow?

Reminder, keep shinny side up.

[rocketwheels]

funny thing about the "up" arrow, it keeps coming on when I'm in 5th gear.....i can't go no further up than 5th !

That was a common programming issue. I remember getting a notice about it for my old YJ. It was an "it may happen, and if it does ... replace the ECM, if it is of issue, otherwise it does no harm and can be ignored" kind of notice.
