Sorry the S1 is described as a wheel or tiller pilot, however if you have a pump to put into the system, I think you will find that it has three ports, one is connected to the helm pump (on vetus there is a blanking plug that has to be removed) your existing pipes from helm to ram have to tee'd into the pump, better to use flexible hose so that you can change over ports for port or starboard correction. Again Raymarine is all on line.
