Drive with just a smidge of common sense and you don't even /need/ a brake controller for a 4k trailer. Should you have one? Yes. Is it a have-to? IMO no, again, with a little common sense. Shucks, with my luck these days, the trailer brakes wouldn't be working anyways......

So long as you can get it working. If not, the new controllers are stupid simple to install.
For a quickie install sure. It shouldn't hurt anything so long as you unhook the power wire going to the plug and re-route it to the new controller.
Yes, that wire is blue and is already disconnected from the old controller.The connection to the trailer plug. There has to be a wire going to the trailer plug from the old controller.
Actually All electrical connections are disconnected from the old controller.I'd probably disconnect the power off the old controller too just for good measure.
So................ which controller?
