Return that solid wire and get stranded wire. Stranded just means it's a bundle of wires twisted together. That wire you have will be impossible to solder. Also, make sure you get 18 gauge / awg. Higher numbers are actually smaller wire. 20 gauge stranded wire would be very thin, making it hard to work with, adding resistance, and it would heat up and possibly burn the wire.
A 1A fuse would be good, but even a 3, 5, or 7.5A would work fine. Lower fuse ratings are theoretically safer but any of those size fuses would protect you if your wire were to ground out.
That's a lighted switch. If you want the light to work, you'll have to hook it up to it's own power source, ie tap into the neon power connection.
Those are the small quick disconnects. Try slipping it onto the pins on your relay and you'll see what I mean. That's what I hate about Radio Shack. That and their high prices. See if you can find the wider quick disconnects at a mom and pop electronics supply store.
Did you get the Channel Lock 909's? Some strippers?
I'll try to keep an eye out for this thread but if you have any questions, PM me and I'll help you out. Good luck!
