There is no official retrofit. I am sure it can be done.
The early units used a hydraulic pump to do the open close. I think 2009 or 10 was the last year for these.
The later units just added motorized gas struts to open the door. Replace the regular gas struts, add the correct wiring, There is a close switch to add in the truck and perhaps or perhaps not a open close sensor. Then code the modules. That should do it.
