HI, We want to buy a Raymarine EV-200 autopilot and we have an old Garmin TR-1 auto-pilot installed. Can we use the pump from the Garmin TR-1 with the Raymarine EV-200? It would save us a lot of money... but we are not sure how to connect the Garmin pump - we have on power cable and the other cable for the pump sensor... any advice or help would be appreciated. thank you
