You were most likely looking at a early vintage TR-1. The Tr-1 Gold autopilot Only has 4 wires, 3 are barried in the back of the transum area. The only exposed wire is connected to the remote, as with all other steering systems. I mentioned there will be a wireless remote available soon! Oh also Our Electronic's are encapsilated in a potting compound(waterproof) Im happy to awnser any questions about our autopilots any of you may have.

Keep on Trollin!

Pete/TR-1
