The old warn winch 2500 gave up the goat . I picked up a no brand 3500 winch with no Manuel . What I would like to know is. Can I use the existing Wiring and just remove the old and replace with the new.There is nothing on the 3500lb one that relates to amps or anything. Im sure I can get it to fit with a few modification and really dont want to tackle the wiring. Any help would be appreciated.
