1998 plymouth grand voyager 3.3l engine.

I got the side dinged last week aqnd am interested in taking off the door and remove interior trim to see what i can bang out. There are 2 bolys at the bottom of the door that look easy enough and 2 on the rollers on the back, however there nis a cable connected at bottom that looks tricky,,,, any ideas? once i get the door off need advice to get trim removed

thanksforanyinput
