btw the loop in the powerlet plug is to shorten it a squeek so it doesn't hit the exhaust in the dual powerlet outlet.....again
I usually leave the powerlet plugged in and use the other end, (red/black) barrel connection, as the disconnect.
The two wires you see plugged together in the liner are for the gloves. As they are shown, the gloves are hooked to the jacket. If you unplug it, you then route it to the second input of the controller and the gloves have their own circuit.
The red plug is both v+ and ground (coaxial connector) The other end either goes to the powerlet plug I showed in the picture, or to the harness which has 2 leads one for ground one (fused) for v+.
Both connections have to be made or the electrons spill out and they will cause you to loose traction. DAMHIK.
