Wellcraft Boat Owners Forum

I bought a used 210 coastal and a bunch of the radio wires wires weren’t connected. I was able to find the hot and ground wires, but I don’t know what to connect the accessory wire to. I have the boat wiring diagram but nothing says accessory. Please help.

Thanks.

Just joined, but did you get it figured out? If you're talking about VHF, my Uniden has extra wires for exterior speaker, signal in for GPS and other. But I guessing you are talking boat side?
