There are a lot of variables that can change how much/what kind of wires to use, but most important is safety and what end product you want ot end up with.

I wish I was able to drive yo meet you, but I am unable. if you ever get in or around Tupelo, let me know. I don't charge for help as long as you want to learn and promise to teach a friend or two //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
