fiatslug87 Posted February 5, 2016 Share Posted February 5, 2016 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. Link to comment Share on other sites More sharing options...
D Standard Posted February 5, 2016 Author Share Posted February 5, 2016 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. Link to comment Share on other sites More sharing options...
schardein Posted February 5, 2016 Share Posted February 5, 2016 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! Link to comment Share on other sites More sharing options...

cruiser54 Posted February 8, 2016 Share Posted February 8, 2016 Upshift indicator light on manual trans models. Supposedly, if shifted then it would meet EPA fuel mileage estimates. Link to comment Share on other sites More sharing options...
shelbyluvv Posted February 8, 2016 Share Posted February 8, 2016 The up shift light is my overdrive off light on my V8 powered MJ. Link to comment Share on other sites More sharing options...

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.

Rockfrog Posted February 14, 2016 Share Posted February 14, 2016 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.
