[CA] [CA11] SmartController charging cable wiring

[jrpsmith]

We recently purchased a sailboat with an existing complete Raymarine system, including a wireless autopilot SmartController. The previous owners had the SmartController's charging cable hardwired into the 12v system, but in an awkward location. I went to move it, but can't find any install notes on which wires on the SeaTalk1 cable to use. There were only two connections before, so I assume that it was the regular Seatalk power (red positive and bare/shield as negative), ignoring the yellow data wire, but would like to confirm before reconnecting. Thank you.
