Those look nice and clean. Good job on the install.

30years of experience in mobile industrial electronics has taught me that it's good practice to put the connections on the bottom or at least on the vertical sides of any controllers you install whenever possible. The textbooks say to do that... the real world tends to be a great educator but not very forgiving.

The best way to do it is place the connectors on the bottom of the controller with a drip loop in the cables underneath to encourage the water to go elsewhere. Downward pointing terminals are not likely to collect standing or any other water in the connector shells outside the seals that doesn't quickly evaporate.

Connectors placed on the Vertical sides will shed most if not all of any small amounts of water spilled on the controller but they can still stay wet for several hours.
Connectors on top can get a large enough volume of water pooling in the connector around the wires that it will not quickly evaporate. Sealed or not... they will eventually leak and corrode if water is sitting in the connector shell.
