The Project Humvee Battlewagon came from the US Army with a Mile Marker hydraulic winch, but no winch controller cable. I ordered an NOS HMMWV winch control cable online (NSN 2590-01-448-1105, P/N 12447171) (eBay link), but was disappointed to find that my winch would only work when the switch was pressed towards “OUT”. The winch controller switch I ordered would not make the winch work when pressed towards “IN”. Since the winch control handle was new, I assumed that there was a problem with the winch, wiring in the HMMWV, a winch control solenoid, etc. That turned out to be a false assumption.

Here is my winch and the black HMMWV winch controller cable I ordered:
If your HMMWV Mile Marker Hydraulic winch will only pay OUT under power, not IN, AND you have the black HMMWV winch controller NSN 2590-01-448-1105, P/N 12447171 then this simple change to the winch control cable plug will fix your controller.
If you have any other Humvee winch controller cable, then I have no idea if this might work.
All you have to do is swap black and white pins in the controller cable’s plug. This is easy. However it took me a while to figure out how to open the plug, to get access to the pins. This Cannon_Plug_diagram_CA3106E14S-1PBF80 helped, but still didn’t show that the inner ring is threaded to the cannon plug housing. Once I had the plug open it took all of about 2 minutes to carefully switch the pins. Once reassembled the Black Humvee winch controller worked perfectly with my Mile Marker hydraulic winch.
If the instructions below don’t fix your problem, then consult this HMMWV mile marker hydraulic winch troubleshooting guide (link).
