@Sbrown ... Your winch has a solenoid, mount that under the hood somewhere, wire from the winch to the solenoid, solenoid back to battery. Use cables supplied with winch or get some good stuff. Winch draws a lot of power, don't want to skimp on that and burn it up.
I bought a good set of 6 gauge jumper cables and cut the ends off and used it. Both wires together, thick coating and easy to run. Dedicated for winch, mounted the sealed solenoid/wireless control box to cross member near dash.
IMO, install a power block somewhere for future hook ups. Then you only have the two cables running into the battery box.
And there will most definitely be future hooking up!
