So it should come as no surprise that the original electrical system of our ’56 CJ-5 is simple when compared to the wiring and computers of the ’98 XJ donor. We spent time with an original factory service manual for the Cherokee pairing down the factory harness. We removed items like the wiring and computer for the air bag system, power mirrors, power windows, third brake light, and a ton of other early Jeep non-essentials. Here is the pile of wires we are hoping we don’t need! Only time will tell when the power is applied to see if we chopped out too much.
