options of adding Cruise Control to my TJ
2002 4.0 5 speed. no factory cruise or cruise wiring taped back on the wiring harness by the master cyl.

1) buy the oem kit for $519

2) aftermarket JCWhitney style ~$100 Audiovox

3) anyone source junkyard parts from 4.0 cherokees or grand cherokees??? they produced millions of these jeeps with cruise control

- wrecked wranglers are non-existent in junkyards around here. I'm guessing its probably like that all over the southeast.

- the later model cherokees had the same steering wheel buttons as my TJ would have.. more than likely have the necessary clock spring for the steering wheel among other parts. my local pull-a-part has 13 models so I'm guessing I could find 99% of what I need to convert it over.

my only problem would be the factory wiring that mine didn't have.

does anyone have the kit they sold with the optional wiring? I could just borrow for a few dollars and copy the wiring? maybe I could share that with the fellow members

thanks for the help

I'm also interested in adding cruise to an 01 wrangler. So let me know what you find out. Too bad they used the vaccuum operated cables.

been just scoping craigslist for used grand cherokees/regular cherokees looking for engine bay pics to see whats up..

seems like those two trucks had the cruise mounded on the pass side and the intake tube on the driver's side.

the instrument cluster even looks the same in the old cherokees as my TJ. same layout/size

I won't be able to hit up the local pull a part until next week..

maybe there is some site I can go to so I can cross reference part numbers?

anybody know of a good online OEM part catalog??

I installed an after market cruise on my 97 and it worked very well. I can't remember the brand, but I bought it locally here in Omaha from a auto accessories company. It was less than $100 back then. PM me if you want to contact the company.

I dunno...

seems like 99% of the parts can be gotten from a 97-01 XJ Cherokee. those are alot easier to find in the junkyard than wranglers

so I guess I'll go fish and keep ya'll updated.

deathphoenix99 06-11-2010 11:10 AM

03 rubi, do you have a manual transmission? And where did you pick up the wiring for the vss constant? Or is it tied into engine RPM if you have a manual?

lukem80 06-11-2010 12:49 PM

here is some VSS data for aftermarket cruise installs

CCS-100 Cruise Control Instructions Here! -

here is some OEM instructions I found for 03+ TJ's without cruise

Amen... lol

$35 from if you pick up the parts and make it yourself. Just gotta remember to disengage before clutching and/or stopping.

I have cruise on my sahara
but also ABS
When you hit a bump the
ABS kicks the cruise off

lukem80 06-15-2010 10:29 AM

so far I have an 01 XJ cherokee engine wiring harness for $50

a clock spring and steering wheel buttons off the same cherokee for another $50


just need the under hood servo now. the cherokee one mounts on the pass side.. the TJ ones mount on the driver's side... they look the same though.

I'm going to take apart the harness of the cherokee and see if I can't 'graft' the piece I need to make the cruise work.

Good luck to you Lukem80, I'm doing a test of cruise control, but I'm trying to see if I can adapt a chevy electronic cruise control to work. I think I may be able to.

lukem80 06-15-2010 12:01 PM

I think any cruise control would only need:

some sort of speed control signal (like VSS)

a servo hooked to the throttle body (vacuum/electric)

something to tell it to turn off when you hit the brakes/clutch (wired into brake/clutch switch)

and the control module... you know.. the buttons

what are we gonna do when all the new cars that are drive by wire become old and needed to be modified ???? SOL

deathphoenix99 06-15-2010 01:03 PM

I already know what I need, I added cruise to my truck, it's just trying to find the VSS output to be correct for my application.

I have all the factory cruise "add on"(Under Hood Harness Only) from a 00 TJ. Bought from dealer, installed by me, vehicle totaled, harness removed. The rest was sold already. Surely someone can use this. Here is a link to my ad, TJ and XJ parts for sale for trade -

lukem80 06-24-2010 10:57 AM

here is a picture of the pinout for a 01-02 speed control servo

the first two wires go back to the PCM and the last two are the light switch for the cluster and a ground.

here is some mopar instructions on how to 'center' your used clockspring (right click, save as, then maybe you can 'zoom' in on it in picture viewer)

lukem80 06-24-2010 02:34 PM

Powertrain Control Module C3

I believe it to be the one on the left of the computer. FSM says it has a gray top.

just gotta figure out the last wire that interacts with the battery temperature sensor... FML

lukem80 06-24-2010 03:16 PM

Brake lamp switch (located underneath the dash by the brake pedal)

you need V32 and V30 also for cruise control.

lukem80 06-24-2010 03:52 PM

after looking at this crap all afternoon...

I figured out that.. if your 01-02 TJ didn't come with cruise and you don't have the wiring you could skip having to replace the clockspring if you just decide to mount the cruise control buttons elsewhere.

so all you'd need is the underhood servo throttle cable thing, cruise control buttons, and a homemade wiring harness. maybe $70 bucks total

lukem80 06-26-2010 02:24 PM

found this website

Mopar Connector Repair Kit Website

that led me to the part number

Mopar Package #

seems like you can go to a dealership and get this for the speed control servo. its the 'pigtail' and some wires to make your own harness. I think it can't be more than $15

you can find other part numbers for engine sensor repair kits on there also.
