Can someone please help me with this? Wiper motor/wiring issue... (with pics)

If the motor is correct to the car and has the original wiper switch then the harness is incorrect as you have noted. It is a 2 speed harness. If I am correct the harness plug is attached directly to the wiring from the motor on 3-speed. From the pics you posted it appears the harness was cut just past the strain relief. Not sure if there is a new harness that can used and soldered in but. Go to mymopar.com and get the factory wiring diagrams. Perhaps you can adapt the 2 speed harness to work.
