Strokermjcomanche Posted March 24, 2019 Share Posted March 24, 2019 It's Been kinda hectic lately and haven't posted in a bit , but I grabbed the Cluster / extended idle switch and Ecu out of a 95 XJ . I'll be installing it in my 89Mj that has a complete 95 XJ swap in it . My question is , the extended idle is plug and play right ? Also ,weren't most of these clusters dummy lights ?

eaglescout526 Posted March 24, 2019 Share Posted March 24, 2019 Isn't that a police XJ cluster? Link to comment Share on other sites More sharing options...

This cluster came from a Cherokee that had no real options other than the complete skid plate package and rubber flooring , I see no real evidence of it being a police XJ to be honest.

But that's what it is, because that's who Jeep sold them to. Link to comment Share on other sites More sharing options...
schardein Posted March 27, 2019 Share Posted March 27, 2019 I've pulled two of those clusters. One was from an XJ that had a column shifter like an MJ, so it was plug and play in my MJ. I didn't bother adding the extended idle switch, I have no need for it. As for plug and play, my understanding is there is a pin on the computer that gets either a ground or positive feed from the switch and that engages the high idle function. That pin is likely missing a wire and has a plug, so it will just be a matter of pulling the wire & pin from another XJ/MJ computer harness and adding it to yours. Then feeding the other terminal of the switch the proper ground or positive connection. I found a second cluster and the XJ it was in was a console shift. So I'm saving it in case I convert to column shift when I do my 4x4 conversion. Right now I am leaning towards keeping the console shifter. Neither of the XJs showed any signs of being a former police vehicle, other than the cluster. The one with the console shift did have seats with a smooth vinyl face, which I found unusual. I also noticed it made sliding in and out of the XJ much easier than fabric and thought that would be a benefit to police car where the driver might be getting in and out often. I posted about it and got several replies of people who had XJs with smooth vinyl faced seats. So I concluded it wasn't that rare. Every police cluster I have seen or seen pictures of had gauges, not idiot lights, but no tach. When I installed the police cluster, I matched the mileage on the speedo exactly to what was on my original MJ cluster, down to the tenth. Link to comment Share on other sites More sharing options...
schardein Posted March 27, 2019 Share Posted March 27, 2019 Also, notice the second pic of the extended idle panel, the plastic is gray instead of the more common white. I've seen a couple switch panels made of gray plastic like that, but do not know it's significance, if any. Link to comment Share on other sites More sharing options...
schardein Posted March 27, 2019 Share Posted March 27, 2019 Also, my favorite feature of these police clusters- they are the only "blue" faced clusters for the 91 and up 4.0HO with electronic speedos that have a trip odometer.
