Cruise Control

[Jess]

Has anyone ripped a Cruise Control system out of an XJ and put it in their MJ? I probably won't get to it unless its much easier than I'm expecting - but I'm driving up to Vancouver, BC in August (from Sacramento, CA) and it sure would come in handy...

 

89, 4L

I haven't done it but have been thinking about it. I am interested in hearing an answer to this as well.

I'm interested as well. Just got this 89, plan to swap out it's AC, tilt, cruise,intermittent wipers. Even got a better 4.0 than the one that is currently in the MJ. Don't plan on any of this too soon as the MJ is still undergoing its 4x4 conversion. If I do get around to it soon (Sometime this year) I'll make sure I take lots of photos.Hopefully somebody has info on this.

Oh Yeah...... got the XJ for 175$ :banana:

Looks like the pop's and I are going to head down to the Pick n Pull soon (not sure when exactly) and take out an XJ's cruise. I'll bring my camera and take pictures for reference and I'll try to write a guide of some sort.

 

If anyone has done it and has some preemptive advice, let me know :)

I've installed it in my 91; took about an hour. All the wiring is built into the harness and it's pure plug-and-play. You need the speed control servo, the cable that runs from it to the throttle bracket, and a new stalk with the cruise wire. But I suspect all you guys are talking about Renix vehicles, that's a bit more involved. :D

I have an '89 4.0L which I believe has a Renix? I don't know the engines inside out yet. Whats different about it (The CC system)?

yes, I've done it

actually, if you have an automatic, I have a good complete cruise control system I don't need any more.

 

remember, cruise control wiring etc. is different between auto and manual...with a 5 speed there is an extra cutout sensor on the clutch pedal, so you need the wiring to match that if you have a 5 speed

[Jess]

I have a 5 speed yeah :(

[JeepcoMJ]

I have a 5 speed yeah :(

 

 

 

I'll talk to TNT tomorrow. he has my 89 5 speed, which had cruise that worked great. I'll try and get that for you if you can't find it at the junkyard

I've got a 90 4.0 Automatic. I'd be interested in the cruise control.

1991-1993 XJ/MJ use an electric speedo.

 

1987-1990 XJ/MJ 4.0L use speedo cables.

 

For cruise and intermitent 87-90 you'll need both speedo cables, Cruise control module, intermitent wiper module, CC/Wiper switch/stalk and/or internal column switches.

It may be easiest to swap column, cables and modules from coresponding years. There should be the rest of the wiring under the dash already.
