Some 2002 through 2004 Dakota's had a relay operated with the key in the towing position that required the removal of fuse 8 to prevent excessive current drain.
My 2002 Dakota did not have a large enough current draw, about 250 ma, to warrant removal of any fuses. Most Dakotas 2002 through 2005 have minimal current draw ,again only the transmission light which draws 250 MA, so Dakota's can be towed for days without drawing down the battery.
If you measure excessive current draw and the information is not in your owners manual consult Dodge engineering for the proper fuse. Prior to 2005 the fuse was 8.
