I would go with hard wiring it. I have not seen a wireless remote with the ability to finally bump the spool yet.
This what I did.
If you are going to have the switch in a location that can easy be hit, you're going to want to have a sepret on/ off switch to power the on/off/on momentary switch. this is because as you go down the trail if something bumps it you are going to spooling in or out.
draw power from a third sores in the cab. I ran a extra fuse block into the cab for accessories. this way you are not running a live wire all the way from the front to the cab and 3 more back. I used the on/off switch to power the momentary switch so very easy to set up.
And two tips place the switch in a easy to reach place when you are laying in a very awkward position and the one that took me some time to figer out because no one said it, with a warn winch (5pin) you have to ground the switch to the motor.
Good luck and don't let the smoke out
