Hello. I wish to assist in obtaining circuit depends on the pattern of the circuit (below) to run engine HDD has four sockets. Thanks for your help. Please note that I have carried out the circuit mentioned previously (the drive controller circuit HDD has 3 sockets), and used to run the engine 4 sockets, but take care of oscillatory movement?
