I have a 1990 chief , i am trying to add an Overhead console from a 1990 xj i have the console and the mounting brackets and the wiring from the donor vehicle , my problem is the wiring, I have not been able to find a write up for this, involving an MJ. have no problem having to modify the harness, and electrical work does not scare me. It does appear i do have the ambient sensor temp in the middle of my bumper. i would like ambient temp to work, as i do live in Texas. if someone could post a link or so or even pictures on how they did i would be very grateful.
