I have a minor issue with my wiring, i did my trans/case swap today and ran into a little problem.

my 91 2wd mj speedo wiring is different from my 94 xj aw4/231 combo

here is the colour scheme for the wiring:

 

plug on 91 2wd aw4: 2 wire>

white/orange stripe

black/blue stripe

 

plug on 91 body harness: 4 wire>

white/orange stripe

black/blue stripe

black/red stripe

black/grey stripe

 

plug on 94 aw4/231: 5 wire>

orange

black

white/orange stripe

black/blue stripe

black/red stripe

 

also on my 91 body harness a couple of inches from the 4 wire plug the is a 2 wire plug>

red/black stripe

black

 

does anyone have a diagram or the knowledge to help me sort this out.

 

thanks

Why can’t you just swap the speed sending unit/gear thing over from your old case? There’s just 1 bolt holding it in should be a direct swap

 

:Edit:

Now I see that its a 2wd to 4wd swap sorry... the cable driven sending unit on my 2wd AX5 looks a lot like the one in my cable driven NP231 I haven’t looked at both of them closely though. Maybe my original idea might work? It’s worth a shot anyways.

 

The extra wires on the later years might be to keep the odometer from going backwards when backing up

both transmissions are electronic speedo's

its just a matter of me splicing in the plug from the 94 harness to the 91 harness. i just don't know what all the wires do!! if i cross reference a 91 FSM with a 94 FSM ill have it all figured out... only i don't have them!
