switching to aw4 solenoid hook ups?

[tarmac2dirt]

Hello once again,  iam looking at doing a 4x4 swap into my 88 MJ. The parts are coming from a 92 xj which has the AW4 and my Comanche is a 2wd standard trans. My biggest concern is hooking up the aw4 solenoids to work on the renix system with out swapping the entire 92 wire harness. I have a complete 92 xj so I will have everything available. Will it be a nightmare swap? Thanks

The '92 XJ still had a separate TCU, didn't it? So use that.
