I have 1996 4.0 aw4 2wd xj that we converted to 4wd. The 98 231 has a different speedo plug than the 2wd one that plugged in the trans. Help needed to identify wires on the old plug that correspond to the pins on the 231. Plus one 2 pin plug that has no home with the 4wd setup. It appears I can’t post pics so I don’t know how to provide y’all more info.
