CoastChief Posted March 2, 2020 Share Posted March 2, 2020 Was cleaning my engine bay and I found this covered in grime. I cleaned it with CRC and gently brushed. I just can’t find where it goes or what it may be for. Link to comment Share on other sites More sharing options...
Minuit Posted March 2, 2020 Share Posted March 2, 2020 Low washer fluid level sensor. Easy option to add if you feel like it. Link to comment Share on other sites More sharing options...
eaglescout526 Posted March 2, 2020 Share Posted March 2, 2020 Minuit he can't add it. I tried to. It is like the wiring is there but not on the dash side. I think only the HO's are wired for it but the Renix MJ's aren't. I could be wrong and just have faulty wiring somewhere. CoastCheif, try jumping the two pins together and see if anything happens. Chances are the bulb isn't in that spot. Link to comment Share on other sites More sharing options...

Chances are the bulb isn't in that spot. That would be a bafflingly stupid but not-so-surprising twist for them to have included half (but only half) of this circuit. I know for a fact a '91 is wired for it, but without the bulb in the cluster. Do not expect the cluster to have the bulb. But yes, you should try a bulb in that position and see if anything happens when jumping the pins of the connector. My bad for the assumption. All of this assuming a light that annoys the piss out of you when you use around half of your washer fluid is of any interest to you. Link to comment Share on other sites More sharing options...

After reading Hornbrods post on it I decided to hunt down one of the sensors and I fiddled with the damn thing for a couple hours. Tried the bulb in different spots just incase and I got nothing. I think the circuit is there when there is the rear wiper wiring. Oh Ohm! Link to comment Share on other sites More sharing options...

Nothing on the interior for a rear wiper/washer switch of course, but the pump connector is there. Link to comment Share on other sites More sharing options...
eaglescout526 Posted March 2, 2020 Share Posted March 2, 2020 Same. Second pump connector is there on mine but I'm pretty sure it is dead. Link to comment Share on other sites More sharing options...
54bobby Posted March 2, 2020 Share Posted March 2, 2020 i have the same unused connector in my 87 Link to comment Share on other sites More sharing options...
87MJTIM Posted March 3, 2020 Share Posted March 3, 2020 Jeep used the same wiring harness for XJs. The second connector powers a pump for the rear window washer on the XJs. Link to comment Share on other sites More sharing options...
Ωhm Posted March 3, 2020 Share Posted March 3, 2020 88XJ Electrical Manual shows Low Washer Fluid is powered up by the Radio Fuse. 88MJ Electrical Manual doesn't show this. Not much information in either manual to help anyone. Minuit photo of dash (Low Washer) show bulb is in a different location than that of the 88MJ Manual. I think (since its there) Engine Harness is equipped, IP Harness is not. Link to comment Share on other sites More sharing options...

eaglescout526 Posted March 4, 2020 Share Posted March 4, 2020 Yes. XJs worked fine for that feature. Renix MJ's are not wired for it. Link to comment Share on other sites More sharing options...
