i took a 3.5mm female banana plug and cut the rear and soldered it directly on the motor
so i can plug 3.5 bannanas either from the back(cougar) or from the front(B44)
in my next version i want to drill a hole at the male bannana and put a screw after i plug it in, at the other end so its going to be safe in place.
