Dad Skis No no no. They may NOT always work. I think it was 1997, maybe 98, Chrysler changed the system and had two small switch pods. This LOGIC has stayed the same for a number of years, but the resistor values have changed.

The 1998 year is unique and the 1999 and beyond (I'm not sure how far) is unique. So, switch panels from 1998 only work with the computer from 1998. And switch panels from the 1999 and beyond only work on computers from 1999 and beyond. I don't know about 1997 and earlier.

I have NEVER seen a schematic in any service manual that lists the correct specific switch resistor values, but in one of these threads (#145) I posted what they were for at least two of the variations.

All other parts are 'generic' like the clock spring and servo and can be swapped, if they physically fit. I guess there are a few 'mechanical' issues for certain years.

Also, I was told that after 2001 the switch values were almost certainly the same for Cherokee and Wrangler, and were suspected of being the same from 1999 on, but I have not been able to personally verify that.

See message 145 in this thread for my original posting on the resistor values. These are value of the switches OUT OF THE SYSTEM. That is, disconnected and read directly with a good quality volt/ohm meter. But here's what I found

So, here's the differences between the switches.

------ 1998 --- 2001
None-- Open --- 19K
On --- 920 --- 440
Set --- 6.6K --- 4.1K
Res --- 15K --- 8.35K
Coast -- 3K --- 2.5K
Cancel-- 0K --- 1.15K

The big difference is that in 1999 (since the 2001 switches work in my 1999 model) is that Chrysler went to resistor values for ALL STATES. There is no longer an 'open' mode and no longer a 'dead short' mode. Everything is now specific values. I suspect they were trying to fix a problem with RF interference in the vehicle.

young-blood If the switches fit on your wheel then they will probably work. The first set I tried were a slightly different shape and did not fit properly or work. I don't remember the last year of the cherokee but if you have an '04 I'm gonna say it's unlikely? Best and safest bet is to use '04-'06 wrangler switches.

WWJeepDaddy My Rubicon is an 04 and I was wondering if you know what years TJ have the correct cruise control switches and if you know if there are some other Jeeps such as Cherokee's that have the same steering wheels.
07-22-2013 12:05 PM
cuder Good to know you got it working. I wish I had done the install years ago.
07-20-2013 04:35 AM
Benford WELL i FOUND THE PROBLEM. I NOW HAVE CRUISE!!

I had the red/limegreen wire switched with the limegreen/red wire at the plug C3,
I suppose I got in a hurry, just glad I figured it out,

Thanks for everything, I could not have done it without this thread

I love the Internet!!!!!!!
07-18-2013 04:33 AM
Benford OK....I will check it out
Thanks
07-17-2013 03:12 PM
cuder The switches are the same. You need to trace the wires and make sure the cruise kit harness is the right one.
07-15-2013 04:56 PM
Benford All I can think is maybe the switches are the wrong ones, I guess 2001 switches are different from 2000, worth a try?
07-14-2013 07:12 PM
Benford Still no cruise, did everything you guys said and still no go,
I started with a factory cruise kit I bought online, for a 2000 TJ, mine is 2001, figured they were the same,
Had to buy a different clock spring, coz the one in the kit didn't fit,
has wiring harness with the kit so I had all the correct colored wires,
hooked up everything as to your instructions because the kit was missing instructions, no dice,
pulling my hair out...spent lots of money...
don't know what to do next ,
06-28-2013 02:48 PM
cuder I got a clock spring at the wrecking yard from a 2000, because the one on the column I was putting in didn't work.

The column I had put in my Jeep was a 2001. I took the clock spring apart and switched out the center for the other.

So, yes you could use a wire splicer. But the ones that I numbered 1 and 2 are hard to get to, I had to dig through the wires to cut them.

What model Jeep do you have?

I have an 01 and it has same looking connectors, it has the blue and yellow stickers on it, I can see that it would be hard to get to those wires through the speaker hole,
Thanks for explaining it so clearly , it really doesn't look that hard,
I have everything mounted I just like the wiring part, and waiting on the clock spring to come in, I had the wrong one,
NOTE to anyone doing this, the clock spring is different for 2001-2002 the hole in the center is bigger , 97-00 is too small for the steering shaft
Thanks,

There are 2 connectors in the block that have the 3 wires you need to splice into. You will be looking at the back of one marked with a yellow sticker and the other is blue.
#1: The dark blue/red one on the left goes thru the fire wall to the same color wire on the solenoid. This wire is coming from the brake light switch.

#2: The yellow/red one in the middle goes to pin 11 of the ECM C3. It is also coming from the brake light switch.

#3: The red/light green one on the right goes to pin 32 of the ECM C3. It is coming from the clockspring.



Then as young-blood has already shown:
#1: the tan/red wire from the solenoid goes to pin 4 of the ECM C3.
#2: the light green/red wire from the solenoid goes to pin 5 of the ECM C3.
#3: the black wire goes to the ground point on the firewall.


I wrapped some tape around the 3/32 drill bit about 1/4" from the end, so I would'nt drill too deep when drilling out the dummy plugs.

I hope this helps someone doing a model around 2000. It's really not very hard, just alittle time comsuming. But, it's great having CC.

So when you spliced into the wires under the dash , did you just cut these wires and attach the new ones, the pic looks like I see a cut wire hanging there, do these not go to anything else? could a feller just use those wire splicers on these ?
Thanks,
Benny

Thanks alot young-blood, I owe you a beer or six. Send me a PM if you ever have some free time. Also have you ever checked out the Lone Star Jeep Club? Check out their forum.
Lone Star Jeep Club

We have a new guys run coming up Sunday in Bridgeport, if you read this before then you can come on out, you don't have to be a member. But, you do have to have the state OHV sticker.

Thanks! I usually wheel alone but I have been thinking of getting together with a group to go wheeling now that I have a new lift and 35s. I'm not sure what might turn out to be the weak link first. Axles, steering, or brakes. I don't replace or upgrade stuff till it is fully worn out or broken so you just never know. Will pm you.
06-02-2013 07:48 AM
showtime Thanks to this info i now have cruise in my 04 tj sport,picked up the acuator from a 02 tj and the switches from a 99 Grand Cherokee, plug and play .GREAT

Good luck with the install!
Yes, it didn't have tilt, cc, or intermittent wipers. The column I bought has all that,

I pulled my column out yesterday and found the the bottom end of the shaft is different.

Also the wiper switch connector is different. So I have to find a switch for a 2000 now.

So, I'm going to put the tilt mechanism on my column along with the cc buttons and clock spring.


Thanks for the write-up and I know how it is with the babies, I have twin daughters that are 13 yo now.
05-04-2013 04:52 PM
Jeffreybomb Holy crap, I really want to do this. I bought my TJ used and I had a list of things I'd be willing to sacrifice if it meant getting the Jeep I wanted. Fortunately, cruise control was the only thing on that list that I had to give up.

It would be fantastic if I could get cruise into mine. Thanks for the write-up! Sub'd for future reference.

mnatl Thanks to this thread I now have cruise in my '05 LJ. Parts found on ebay for about 140.00, plug and play install b/c I was pre wired.

Thanks again!

AFJeep Update on my Cruise Control install. Worked first time and for about a month and then quit. Turn on ignition and hit ON and the the Cruise Light would flash on then off ???? Checked all wires twice. Had a friend with an 04 TJ come over and we verified the Servo and Switches. Used this thread and verified the resistances. Now what? Of course, as I was looking at the prints, the theory and checking the wires for the fourth or fifth time, my reading from the PCM through the Brake Switch and back to the PCM, was intermittent this time. It was pin 4 on the connector that was intermittent. A connector that I never touched during install. Fixed the connector and all is well. Just another story among a long list that just makes you want to ??????? Just had to share this!

My 2004 factory manual says to wait 2 minutes but I like to be sure. Best single upgrade I made to my Rubicon. Long trips now enjoyable.

Thanks. It is now on my list of items I can do.

Dad Skis So... If anyone needs a switch set from a 98...

Mike
05-05-2012 12:36 PM
Dad Skis That was it!!!

I swapped the switches to the units from the 2001 and the cruise now works just fine.

So... My total job, IF I would have done it right, would have been:

Servo and clockspring from a 1998 Cherokee. $25 for the servo and switches (wrong switches). $25 for the clockspring.

Switches from a 2001 Cherokee. (Yard gave them to me free)

I think you mixed up the ranges...

how can you have two of the buttons pressed a higher resistance than no buttons pressed? And the on and set are WAY too close for reliable distinction between the two.

The sage continues!

Well, the cruise control saga continues.

But... There may be light at the end of the tunnel. I just hope it's not a Kenworth.

Turned out...

The wreck that I got my parts from I originally THOUGHT It was newer than 2000, but it was partially disassembled and I didn't check vin. I got the servo, switches, and the clock spring. I installed all the parts in my 1999.

The cruise wouldn't work. I checked the switch resistance at the computer with a meter from C1-4 to C3-32, and it was wierd. It showed that the Cancel button was a short to ground, but the schematics I could find all showed the On-Off button as the short to ground.

I went and checked on the web. Information there indicated that the same switch was available as a replacement part for 1999 and later Cherokees. (And for up to I think 2005 Wranglers?)

So I went back to the yard. Found what I thought was a 1999. The resistance was different. So I pulled those switches out. (Was kind of stressful, as I wasn't going to sit in the thing since the yard had written 'needles' in big white letters on what was left of the windshield. Too bad, they were nice leather seats.)

Anyway, I went and double checked, and the original jeep I thought was a 2000 was actually a pretty smashed up 1998, which was a different switch acording to aftermarket parts people. And the 1999 with the needles was actually a 2001. However that seemed to cross.

So, here's the differences between the switches.

------ 1998 2001
None Open 19K
On 920 440
Set 6.6K 4.1K
Res 15K 8.35K
Coast 3K 2.5K
Cancel 0K 1.15K

Notice that the BIG difference is the newer switch always loads at LEAST 19K on the line to the computer.

It's raining right now, so I'm not gonna work outside. Have other things to play with, but hopefully I get the wheel apart this afternoon and get the switch swapped and I'll find out if that does the trick!

Dad Skis Well, I went online to see about the switches, and at least one place list the same part number for multiple years from 1999 on. But just in case, I'm going to the yard this weekend and measure a 1999 model.

As to the other question, it shouldn't take long.

Pull the battery connection. About 10 minutes, including wait time

Mount the servo, maybe 15 minutes

Steering wheel. About 5 minutes to pull the bag, and old plates, then 5-10 minutes to put it all together.

Hook up the battery. 2 or 3 minutes.

With the Cherokee, the servo is next to the battery, and you really have to pull the battery out of the vehicle to mount the servo, otherwise it's impossible to get tools in there. Even so, you should be able to do the job in about an hour.

Clock spring though is the biggie. Figure on an additional 20 minutes to pull the wheel. 30 or more if it's from scratch, but it's not much more time is you already have the airbag off. Just be VERY careful of the clockspring. Make sure your wheel is straight when you pull it off and put it back on exactly as you took it off. Scribe the shaft and wheel before you pull it off.
