Don't unplug the fuse. Instead add an electronic flasher in place of the fuse. Of course put a fuse in line too. I have done this and it works perfectly. When you hold the brake your brake light flashes and the sled thinks that as you are releasing the brake long enough that the derate cannot take place. Your buddies won't run into the back of you because they didn't know you were stopping.
Where did you put the 3rd wire (black)?
