When I first purchased the boat, I installed DC and AC  and this year anew engine harness I followed Moyer's directions but did not purchase thier wire kit. I think that was probably a good decision. For all the projects, I just read the directions and followed them and took my time making sure I knew what I was doing. This year I added an AC connection for the computer. Initially, I used soldered connections but have since decided that crimped connections are better. One think I found helpful was that after I had removed the old wiring, the boat was wide open for the new wiring. The one thing that I would improve if I could was the level of neatness at the DC Panel. I redid it this winter when I replaced the engine harness, and it is neater than it was, but there is still room for improvement there. Part of the problem is that I have a large DC panel and that makes it harder to get a result like the ones shown in the sailing magazines. I think doing the circuits one at a time as suggested would help a lot. Based on my experience, the suggestions have been outstanding.

>> I wouldn't worry about sizing the wire. When you do the measuring & calculations, you'll usually come up with answers of #14, 16, or 18 wire. In which case, you can simplify the logistics & possible confusion by wiring everything in #14 and by bypassing the possibly wrong calculations. The extra weight of wire will not sink your boat and you'll wind up with a good conservative wiring job.

He said he used only 4" deep boxes with appropriate plaster covers for every fixture when he wired a new house -  no special switch boxes, junctions, etc. It cost him a little more, but he made it up in inventory simplicity & time savings. I should think the same thought applies to boat wiring.
