wireless winch 3s bec question

[ratmloud]

I was wondering this i am runnning 3s with a bec now and have my steering and 3rd channel for leds, and i want to add a rc4wd wireless winch, can i hook up another bec set to 7.2 and then hook up the rc 4wd winch to the second bec? (would i just use the black and red wires and not the yellowish one from the bec receiver plug to power the winch?)
