4.0l xj 97 motor into yj 87

Hi all
i would like to pick your brains lol,
well not so long a go i had got my hands on a cheap Cherokee xj, i ve bean real busy pulling the block out and transferring that 4.0l to the yj.
I had also decided to go with the AW4 transmission out of the xj.
also decided to stick with the NP231 transfer case from the yj. and got my hands on a SYE KIT .
Everything has gone well up to now, the only thing that's holding me back is the wiring from the jeep xj RHD 1997,
i found this circuit pinout diagram for the Cherokee xj all the wires are numbered in circuit and not function, so that didn't not help much

http://www.jeep4x4center.com/jeep-se...ar=0#toolbar=0

i need to use the yj bulkhead connector and try to splice the xj pinout connector into yj.
Ive already cleand up the wiring loom from the yj that's all labeled and ready to go, i used this wiring diagram,

now i just cant find the write diagram so i can connect it the jeep yj bulkhead.
who can help me out here

I went digging and I dont have one. If you had a real sevice manual you could search the pdf for the circuit on the pins. I will look when I get home to see if I can find one. The Morris online is definitely not searchable using adobe.

find that one we linked up last week or the week before, search for fsm or 87 fsm. we just linked it again so its good.

I don't feel like working on anything at this time so i sold my yj.

when i did my swap, i just looked up the pin out for the donor then matched it up myself, sounds like you need to swing over to the xj page and ask or search there for a pinout.

i stayed obd1 , your wiring a obd2 system in a obd1 jeep. so your gonna have some fun.

I will look when I get home in hour. You need to make s sure it's a 97. There is a huge difference between the 96. The obd 2 was on the 97. You can tell by the engine computer for sure.

You beat me to it 94! The production in Europe lagged the us so he might have a 96. A ECU pic would help to make sure. The 96 through 98 had many rolling changes.

96 is also obd2 , 96 is the odd ball year, they used obd2 system but in a older style body jeep, ive had a 96.

i would suggest just going to scrap yard and grabbing obd1 harness sensors, and ecu . form the looks its alot of work to run obd2, since the obd1 system is 7 volt and the obd2 is 5 volt system, you gotta run o2 sensors, and the wiring on the aw4 trans . ive googled and havent found any real good DIY

Sorry, I looked and didnt have any luck. Try posting to the XJ forum and see if anyone has a PDF copy so you can search it or a different pinout of it.
