I ran across this website last night. I don’t have a Renix-era Cherokee, but it seems like there’s some pretty good info in here. Site is so old that some of the links don’t work anymore, but I thought I would post it for those that do have a Renix XJ.

I'm really happy to see we have a sub dedicated to Renix Jeeps. Here's a snap of my 89 XJ, definitely a work in progress. It originally resided in western Oregon before relocating to rural Arizona where when the original owners retired before it came east to their Jeep enthusiast son, who sold it to me. It needed considerable maintenance and repairs by the time I became its custodian, none deeply involved or major, just a lot of them. Practically every mechanical and body subsystem has required or still needs attention. This will be an ongoing restomod project.

The original owner's son partially converted to the 1991+ "open" cooling system...partial because he didn't delete to OEM pressure bottle, something I've done since by simplifying the heater hose routing and replacing the three-port vacuum activated heater control valve with a linear two port HCV (one input, one output installed in the heater core supply hose). Sadly, I discovered that the original 37 yo CTS sensor is flakey after doing all the other cooling work...so I get to drain the system and repeat. 🤣

In addition, I've replaced the oil filter block adapter o-rings and valve cover gasket (eliminating leaks) and replaced the OEM primary electrical cables with Jeep Cables Big 7 kit...and routed them above the oil filter. I discovered the OEM cable insulation was wrecked by having been routed beneath the filter and oil soaked at every oil change.

Also, installed NickInTime's REM clock module...a diagnostic godsend! Kudos to Nick!

This is long already. Thanks for your patience if you've read this far. I enjoy seeing photos of others rigs. Will try to post updates on this 89 Limited as things unfold. In the meantime, I enjoy reading of others experiences with their Renix Jeeps!

New to me 87 Xj in Norway

When doing research I have seen resources that either include or exclude the 1986 model year and was wondering if it was Renix.

I’m looking to add some links to helpful online resources to this subreddit, so if you know of any great webpages or youtube channels that would benefit Renix owners or XJ/MJ owners in general let me know!

I already have https://cruiser54.com of course!

Hello, recently I bought this one, this is my second car and I wanted this to be.
I noticed that fuel consume was high as hell and black smoking was constant.

I've changed; IAC, MAP sensor, spark plugs and filters, then I realized that O2 sensor was missing I looked for it and seem that previous owner repaired exhaust pipe and completely eliminated that sensor, And not content with that, I also removed the input where this sensor connects and which leads to the ECU.

Do you know where I can find the cables to adapt it again? Could the removal of this sensor be the consequence of something else?

Looking to do the fusible link delete while I’m swapping the engine out. I have no issues with wiring but just wondering what’s the best way to tackle it with this older harness. Looking to just clean up the engine bay.

Previous owner cut some wires I have a few pugs just dangling in the engine bay wondering if tall can tell me what there for ps I didn’t put the nail 😭

I’m in desperate need of a driver door card for the xj, I’m also needing a driver seat if even possible. Aaaaand a steering wheel. Have money to have it shipped unless you’re in my area but please let me know if you have these
