It works for me!!
I have addressed all by making all on the trailer, been this way for years for me, when I had the old winch also. Easy and no wiring issues.
You can see here were I plug in the remote
Battery and all stay on trailer all the time, I just plug in a float charger when boat sits in the yard.
One issue was that the cable was always rubbing the metal, so I took the top roller off the winch and drilled and placed it on the trailer so now the cable just rolls there instead.
