When adding electronics to our boats, deciding on how and where to run the wires may be the more frustrating element of any install.
The previous owner may have run the wires: laid on the deck/wrapped around the stanchions, through a conduit that is now packed with too many wires, or cut unsightly holes in the cabinetry.
It takes time to consider all your options. Sometimes it is better to explore out of the box solutions like building your own cabinet or wire chase to handle your immediate and future needs.
