Hi. Got a HS2 this past weekend and a previous owner at some point had installed a shaker motor in it. I am having trouble finding any information on how to wire it up since the only wire of the 4 coming out of the motor board that is still wired up is the black to a ground harness....the other wires are purple blue and red and not attached to anything. Hoping someone can point me in the right direction! Looks like a pinbits shaker motor.
