Will my speedometer work with a 241 Rubicon transfer case?

[RD3]

Have a 2003 tj and switching to a Rubicon 241 transfer case. Can I make the speedometer work?

Yes I swapped a 2002 sport tub onto a 2003 rubicon frame using the sports wiring and the speedo works

Are you saying that the plugs are the same?
Also what about the 4wd indicator wires. That's definitely different

Ya the plugs are the same i never got the 4wd light to work

Once you swap in the 241 tcase you'll need an external speedometer calibrator like a Speedohealer. A 241 tcase doesn't have a speedometer gear output like your OE 231 tcase does. A 241 has no speedometer gear at all.

Two different questions. He is asking if the speedometer will work and yes it will. Just plug the Sport connector into the 241 sender connector and the speedo will function. The question you answered is how to correct it for accuracy if it is not reading the MPH correctly.

There are probably 50 write-ups on the various forums that tell you have to fix the 4wd light. All you need is the Airtex switch 1S4219 which looks almost exactly like the switch in the 231 but functions exactly opposite. Put that in place of the mode switch in the 241. After that, you can look closely at the connector on the harness and figure out where to put the slot that lets it plug onto the new switch or you can overspend on the AC Delco repair connector PT724 and splice that on.

Is there any difference between the Airtex and NTK 1S4219 switch?

NTK as a company has a superb reputation. I consider Airtex fuel pumps to be junk and wouldn't trust it based on that.

No idea. We've used the Airtex part several times with no issue. If NTK makes the same switch, I certainly wouldn't be opposed to using it.
