''Lever on the dash is a trailer brake valve, so that when descending hills, you can brake the trailer, without braking the Explorer. This holds everthing in line, and leaves you with a set of cool brakes, if the trailer brakes start to overheat and fade.
The winch only powers in at one speed. It cannot be paid out.
You have to lift the drum dog clutch clear and pull the cable off the drum by hand (well many hands actually), or if you can do it reverse up to the casualty, attach the winchrope, drive forward pulling cable off the free drum, then when in your chosen winching spot, engage the winch to pull the casualty out of trouble.

Thanks!
