The ACC switch on a boat is used to power accessories. The wires attached to the switch are usually orange and orange/red or orange/blue. The orange wire goes into a bundle and then comes out with a black wire, while the orange/red wire goes to the fuse box. The ACC bow switch is the orange wire with a blue stripe, and it is used to power accessories at the bow of the boat.

What You'll Learn
ACC switch wiring
In another forum post, a user notes that the power feeds the socket first (darker blue connectors on back of round socket), and then there is a set of wires going from the socket to the switch (light blue on socket to dark blue on switch). It is not clear from this post whether the user is referring to the ACC switch specifically, but it provides some insight into the wiring setup on their boat.
Overall, it appears that the ACC switch wiring can vary depending on the boat, and it may be necessary to consult a wiring diagram or use a volt meter to confirm the correct wiring setup.

ACC switch location
The ACC switch is located in the cockpit of a boat. The switch has two wires attached to it: one orange and one orange/red. The orange/red wire may go to the fuse box on a 5 amp fuse, while the orange wire goes into a bundle and then comes out with a black wire, which is looped in the console waiting to be used.
On an R boat, the ACC switch is yellow/blue and goes from the 29-pin bulkhead connector to the bow. It can be found with a butt connector on it. The ACC bow switch is the orange wire with a blue stripe, and it is "Accessory #4 acc at bow".
The socket is energised based on Master Power, and the ACC switch has no effect. The power feeds the socket first (dark blue connectors on the back of the round socket), and then there is a set of wires going from the socket to the switch (light blue on the socket to dark blue on the switch).
To confirm which wire is the ACC switch, you can use a volt meter to see which wire the switch powers. You can also look under the bilge area lid for a wiring diagram.

ACC switch function
The ACC switch function varies depending on the boat. On some boats, the ACC switch does not currently control anything. On others, the ACC switch is used to power accessories in the bow. The colour of the wire connected to the ACC switch also varies depending on the boat. For example, on one boat, the ACC switch is connected to an orange wire with a blue stripe, while on another boat, the ACC switch is connected to an orange wire with a red stripe.
To determine the function of the ACC switch on a specific boat, it is recommended to refer to the wiring diagram, which can usually be found under the bilge area lid. It is also possible to use a volt meter to test which wire the switch powers.
In some cases, the ACC switch may be connected to a bundle of wires, with one wire coming out and looping in the console, waiting to be used. This suggests that the ACC switch may be intended for future expansion or customisation.
It is important to note that modifying the wiring of a boat can be dangerous and should only be attempted by qualified individuals. Always refer to the boat's manual or consult a professional before making any changes to the electrical system.

ACC switch power
The ACC switch on a boat is used to power accessories. The wire for the ACC switch is orange with a blue stripe, although some sources suggest that the wire is orange with a red stripe. The wire goes into a bundle and then comes out as a black wire, which is looped in the console waiting to be used.
To find out where the wire terminates, you can use a volt meter to see what wire the switch powers. You can also look under the bilge area lid, where there should be a wiring diagram.
The ACC switch is energised based on Master Power. The power feeds the socket first (dark blue connectors on the back of the round socket), and then there is a set of wires going from the socket to the switch (light blue on the socket to dark blue on the switch).
On an R boat, the ACC wire is yellow with a blue stripe. It goes from the 29-pin bulkhead connector to the bow, where it will have a butt connector on it.
