242 TC jumper wire location.

Kycherokee · Jan 12, 2015

I have a 2000 Sport with a 231 TC. I want to swap in a 242 and have been accumulating the parts to do it. Today at the pull & pay I found a Limited with a 242. TC.

I need the position jumper wire. My problem is that I cannot find where the jumper plugs in the engine compartment. Where should be looking for the connection?

Thanks for any help!

If its like the earlier models, it will be a sub-harness that connects to the 242 on one end and the transmission harness on the other. "IF"

Where will you find the transmission harness conection? Where the truck is in the junk yard it is very hard to see where the wire goes from the indicator switch.

On my 91 the jumper wire is about 12-18 inches long. If you can see the end plugged into the transfer case, just follow it up a little ways.

There is a small jumper that plugs into the vehicle harness. The harness is like 12" long and goes between the transfer case switch and the vehicle harness. You plug it into where the 231 jumper un plugs. There is no separate vehicle harness for the 242. E.g. remove 231 jumper, replace with 242 jumper.

See post # 19 http://www.naxja.org/forum/showthread.php?t=29231

The dealerships used to sell a wiring jumper that allows proper operation of the full time dash light after the 231 to 242 conversion (97+ XJ's). The part number is 56041612AA . They may or may not have them anymore.

I just went through trying to find the harness for Urbanyan. No luck at the dealers. I ended up needing a 242 for my ZJ that, luck for him, came with the small harness.

Well, guess my gut instinct my jeep did not come with a 242 was correct. Mine has a 10-12 inch intermediate cable from tc switch to harness. Maybe i should pull it out this summer and make some spares to sell. Great info everyone!

Problem is around here there are no pick & pulls, they don't let anyone wander around the junkyards looking for parts, must be a liability issue in this commie state.
I guess I'll start a WTB thread looking for the part.

you could probably make one with a couple of GM weatherpack connectors and some wire
