So what we have here is the electrode, inserted in my spine. It is then fed into my spine, up into the base of my neck. The silver box on the left is the device that emits the electrical pulse. The gray wire going over my shoulder leads to the battery pack worn on the waist. (which will be replaced by a battery pack implanted beneath the skin.)
From the front, everything plugs in to the battery pack on my waist.
The remote controls amplitude (mA), frequency of pulses, strength of pulses, etc. It talks to the battery pack, which then signals the controller on my back.
