Look closely at the harness and wiring diagrams and you will see that AMC designed it in 4.5 sections:
Front End Lighting
Rear Body (mainly the rear lights)
Transmission (little bit that goes down to the tranny and transfer box for reverse and 4WD switches, not vital)
If you have purchased the Instrument panel harness it will start at the bulkhead connector, do everything for the instrument panel and dash and end in a much smaller connector under the dash that connects to the rear body harness.
To marry this stuff together you will need:
Ford engine harness
CJ Lighting harness
Engine side of the bulkhead connector
Instrument panel harness (which you have)
Rear Body harness
It then becomes very simple, you install all the CJ stuff as God intended and then solder your engine and transmission harness wires into the tails coming out of the bulkhead connector on the engine side. You will need the wiring diagram to understand what each wire does but there are not very many.
