I too am curious if that switch would work in reverse. As in putting a 231 in place of a 241.

I had two "windows" open when I ran across this thread. One was JF (obviously) and the other had the very same pigtail and switch sitting in checkout waiting to be paid for... you saved me $50! Thanks for the post!!

Best price I found for the switch and pigtail plug was from Amazon.com.
Switch Dorman 600-506 $13.64
Pigtail Plug ACDelco PT724 $21.16

Works like a champ

Nice work, added to the FAQ.

It only took me 2 1/2 years to do this.

So my light stops working on my Ruibicon TJ and I want my diffs to lock in 4WL. I followed this thread and get a new switch--and it turns out that Rubicon 241s were built with the original switch. D'oh!

So three questions:
1. Does anyone know where to get the original switch? The part number on mine is not legible.
2. Does anyone have a original switch they don't need?
3. Does anyone need a Airtex 1s4219? I'd be willing to trade for a original switch!

I just installed the 241 into my 2004 wrangler. (swaped out the 231j) I will gladly swap switches with you.

5packer,

I haven't heard anything from you. Are you still interested in the switch swap?

5Packer backed out of the deal. I ended up buying a switch. Does anyone want to buy my 1s4219 off of me? It's never been installed and cost me $34.43 after shipping from Rock Auto. Make me a offer! I'm tired of staring at it on my desk at work!

Using an older switch from a 231 does not work at all on the 06 rubicon. If I put the 241 switch in the 231, then I can get the 4wd switch on in 2wd along with the CEL. The switch button is too long and will not let you shift the t-case. I can fix the shifting problem, but the CEL and getting the switch to function in the opposite position is not possible.

I have not found any info on this.

I know "why would you get rid of a 241?" Cause it goes great with a D30 & D35.
I know this is a old post to reply to, but I came across the answer while trying to figure out what was wrong with my Rubicon's 4wd system. So here goes:

With a Jeep shipped with a 231, the 1s4219 switch wiring directly goes to the 4wd light in a on/off fashion. So it's cosmetic for the most part.

The Rubicons are wired up differently. The 6-position (only 4 positions are monitored) switch on the 241 sends varied voltage to the PCM depending if it's in 2H, 4H, N, or 4L. This is because the PCM only wants the Rubicon to lock it's diffs in 4L while traveling less than 10 miles per hour. So if the PCU gets the 4L signal and the signal from the spedo says it's going less than 10 MPH, then the PCU will allow the lockers to lock.

So putting in a 241 into a non-Rubicon is fairly straightforward--all you need is the 1s4219 switch, assuming you care about the light going on or off.

Putting in a 231 into a jeep with a Rubicon harness is less straightforward--You will need to bypass the PCM so you can lock the diffs (see other posts for that mod) or trick it into thinking it still has a 241 in it.

This was my exact problem.

Your options are:
1. Replace "SWITCH, Transfer Case, 5 Position" (it's really 6 positions, but I digress...) part # 5083138AA.

2. Reset your PCM. http://www.jeepforum.com/forum/f96/h...et-pcm-566770/

3. Find someone with a DRBIII tool to tell you what's wrong. Then either do option 1, option 2, or something else depending on what the DRBIII tool says.

I did option 1 then 2. I wish I'd done option 2 first.

Just ordered these parts from Amazon. With shipping it was like $66 which I thought was a little high but oh well. At any rate this is a great thread! Thanks! Now onto my speedo issue info search...
