i was thinkin the same thing.. cuz im thing bout putin a 3.0 on the front and rebuiltin this 2.5
warn has a dual winch kit. heres a neat vid on how it works.
It would be easiest to wire each winch seperately. You can get a handheld or even a wireless remote for the rear. Handle bar switches are convenient but you will really appreciate a longer reaching control once you use one. Makes it easy to respool and control your cable when your alone. Plus it allows you get out of the way of the cable when your really stuck and putting a lot of strain on the cable. I've seen them break and you don't want to be in line with the cable when it does.I have thought about removing the rear storage box and making some type of mount. Biggest problem I can think of is wiring. How to make a switch from front to rear would be tricky.
Like I said earlier, no reason why you couldn't just wire both normally.This is the easiest way. I think Eric and homie189 are looking to get away from having to use two or( more if wireless also) seperate controls. One selectable control to operate both winches would be a nice custom setup. Won't make any difference to the battery as only one at a time will be used.Why can't you just wire them both up? Why do you need a switch? You wont use them both at the same time so whats the big deal?
