When I put in the Perm-Lock on my 96 1500 (keeps the axle shafts permanently connected), I pulled the vacuum switch from the transfer case (and got rid of all that vacuum hose crap). The 1500 has a 231 transfer case. I don't know if the 231 and the 241 use the same switch or not (I would guess they would...).
I then replaced the vacuum plug thing on the transfer case with an electrical switch (from a 97 - 06 Jeep TJ). It screwed right in. The electrical wire plug from the axle unit (at the CAD) plugged right into the new switch, although I had to add about five feet of wiring (two wires) to have the plug reach from the front of the truck (where it plugged into the CAD unit on the axle) back to the transfer case (leave some slack for axle movement). But it works! Shift into 4WD and the 4WD dash light lights up; shift into 2WD and it goes out. Here's the part number I used:
It's an Airtex 1S2041 http://www.rockauto.com/dbphp/x,cata...LS_1S2041.html
