2000 aw4 into a 95?

[Pookapotamus]

can the sensors and wiring on a 2000 aw4 be switched out with the sensors and wiring from a 95 so that i can put the 2000 into my 95 xj?

will there be anything else that i would have to swap over?

It looks like most people swap the wiring and TCU in there vehicle or do a manual over ride setup. From the wiring diagrams, it looks like after 1996 there was an additional speed sensor for the TCU. This was just a quick search, but I hope there's some useful info in the links for ya

This is something interesting you could do while you're playing with the wires:

it looks like the 2000 will fit but i dont understand this part:

If you have a 1990.5-1996 XJ:

1987-1990 AW4s are bolt-in... as long as you also swap the input gears in your transfer case, or the whole transfer case. Remember that the NP231 input gear cuts changed in 94 or 95 and that the rear output of the transfer case changed from 95 to 96 when selecting a donor. I would NOT suggest this swap unless in dire straits (need to get off the trail, need to get to work tomorrow or be fired, etc) as you are limiting yourself to a rapidly disappearing selection of 21 spline spare parts in the boneyards.
1990.5-1996 AW4s are bolt-in.
1997 AW4s are bolt-in, except you have to cut and splice the wiring harness connector. Again, 5 butt-splice crimp terminals and a few minutes and this is done.
1998-2001 AW4s require more work. All the transfer case input gear info from 1990.5-1997 applies, on top of that, the sensors have changed! You can either build the circuit given here by lawsoncl or swap the transmission tailhousing, sensor drive rotor, and output speed sensor as shown here by Frank Z to make this work.


does this mean that i will have to swap my input gears in my transfer case? i am assuming that it is a typo and it should read 1990.5-1987 then it would say that:

If you have a 1987-1990 XJ:

1987-1990 AW4s are bolt-in.
1990.5-1996 are bolt-in as long as you swap input gears in your transfer case to a 23 spline, or swap the transfer case as well. Remember that NP231 input gear cuts changed in 94 or 95 and that the rear output of the transfer case changed from 95 to 96 when selecting a donor.

this should be ok because i have a 23 spline np242.

or does some one read this differently?

Yeah I think they simply copypasta'd the wrong year range, except you put the changing the input gear to the wrong section. The 90-96 should already have the 23 spline shouldn't it? I think they are saying you have to use that gear in the 96+ t-cases.

I also don't get the 1990.5 thing, good information in there but the way it's written could end up being very bad info!

If you already have the 23 spline to match your tranny you should be gold.
