Do you have more details on the cut/splice to put a 1997 AW4 into a '95 XJ?

I picked up a '97 AW4, the harness has only one connector with 5-pins. My '95 AW4 has the 7-pin connector that routes up the firewall in addition to a 2-pin connector on a short pigtail, by the rear of tranny, drivers side.

NSS's are different, as detailed in the OP.

Re: Everything you ever wanted to know about the AW4

The small connector at the rear is for one of the transfer case lights; if it has a pigtail and is yellow/black and red/black then it's the jumper for the 242 transfer case. Some of the later years had different harnesses depending on how the jeep was ordered

Re: Everything you ever wanted to know about the AW4

Could also be the connector for the output speed sensor maybe? What wire colors? Any chance you could post a pic?

Never seen what ehall described but it would not surprise me in the least.

that looks right. Below is a pic of my 95 AW4, the 91 looks the same.

So both the 97 and 95 trannys have the same 5 color wires (black, white/tan, white/black, violet/white, blue/white) for the speed sensor and solenoids, that must be where the simple cut/splice occurs.

Re: Everything you ever wanted to know about the AW4

I'm doing a tranny & transfer case swap... the swap is this:

Donor = 88 xj with power option automatic tranny and 242 t-case.
Receiving = 93 xj with standard tranny and 231 t-case.

Upon reading this tread I know the swap is a direct bolt up however I'm a little confused and need mor clarification about electrical connectors.

The automatic 88 Donor tranny's plug is 2 wire, it also has the power transmission switch in the dash.

The standard 93 receiving xj has a 3 wire connector and of course, no power option.

My question's are: how do I splice the 88 2 wire tranny plug to the 93 3 wire plug in the 93 engine compartment? How do I get the power option into the dash?

Re: Everything you ever wanted to know about the AW4

I found a 01 trans. To put in my 97 . So the only change I have to make is the speed sensor inside tail housing? I see no mention of connectors being different for swap and computer change since sensors communication to ecm will be different with newer trans and sensors. Is is sensor only or all the items for computer processing?

Re: Everything you ever wanted to know about the AW4

[QUOTE=lawsoncl;245215766]Up to 1993.5, the ZJ 4.0 came with the AW4.



I believe that is correct. The renix TCUs all had grey connectors and can be interchanged. There might be subtle changing in the shifting maps, but they can be swapped. The HO TCUs all had green connectors, and red seems to correspond to the Chrysler made trannies.

They interchange. As you stated, shifting differences along the line. I believe in 1987 they shifted 1,2,3 lock converter, unlock converter as it went to OD, lock converter in OD. 1988 and later shifted 1,2,3,OD, lock converter.

Re: Everything you ever wanted to know about the AW4

When you say "simple Butt crimp" i'm wondering what i'm doing wrong because it isn't simple to me. I put in a 96 aw4 into my 97 cherokee and the 96 has 7 wires, but the 97 has 5. I hooked up 5 of the color coded ones but the jeep won't start.

Do you know which wires go where? any advice?

Thanks in advance for the help and the extremely helpful thread.

Re: Everything you ever wanted to know about the AW4

Are you sure you didn't wire the NSS to the TCU harness and the solenoid harness to the NSS plug on the wiring harness? That could easily cause a no-start... wiring the TCU/solenoid harness wrong should not cause one, it just won't shift right.

I actually figured it it. you just wire the same colors together and there will be 2 wires that are left alone. No idea what they do but the jeep runs fine.

However the 4x4 light doesn't come on, i'm not even sure if 4wheel drive works, i'll look into it. It might be because of a plug at the back of the trans, by the transfer case, it is a 2 wire plug that can either plug into the transfer case or into another plug that is hanging there. I haven't followed it to see where it goes but i think it just goes back to the engine bay and then into the giant mess of wires. Anyone know about this 2 wire plug? i can take pics if needed.

There's a socket on the transfer case that is for the 4WD indicator switch, and one on the tail housing of the transmission that is for the output speed sensor. The output speed sensor one is important, the other really isn't.

Re: Everything you ever wanted to know about the AW4

If the front axle is a disconnect style, the 4wd light might be triggered by a vacumn switch mounted up on the firewall. At least that's how the older ones were setup.

I have the output speed sensor one hooked up right now. Shouldn't they both be pluggin in though? i'd like to see the 4WD indicator on my dash when i'm in 4WD. I don't remember there being an extra plug on the old tranny?

Also mines a 97, so no vacuum.
