Yes, the Foxman has done this! Not very hard. Find a donor truck and get the harness out of both doors. Then get the harness that runs from door to door - It is located just under the windshield and above the heater box. A real bear to remove if the dash is still in the trk. You will have to add two wires feeding the plug in the left kick panel, - one hot with key on and one hot all times. In about 4 or 5 hours you can have it done.
