2wd/4wd swap wiring issue

I have a 91 MJ that i am doing a 4wd conversion on. my donor xj was a 94.
both are 4.0 automatics. my issue is the wiring for the speedo, the connectors are different between the two units. here is a run down of 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

I converted a 94 to 4wd using an 88 trans.

I simply swapped the 94 2WD speedo assembly into the 88 transmission.

what about the other wiring on the transfercase?
