In digging into the wiring of my boat, I have found that things such as the bow lights and other connections have about 2-4 feet of extra wiring that are in the "bundle" of wires. They seem to "S" back and forth and then come out and to the switches. Is that normal? Should I do that with new accessories? I can understand having some excess for movement so they aren't strained, but 2-4' seems excessive.
