    The only soldering I have left to do is the main firing button and the up and down buttons. None of them are holes. Am I supposed to just solder the wire onto the surface? I haven't been able to find any pictures that show it wired up. I also noticed from pictures of the wires soldered to the buttons that there are two wires, but buttons have 4 prongs and I'm not sure how that works either, or how much of the prongs I would need to cover with the heat shrink tubes. Beyond that and maybe getting a better idea of how to install fuses, I do believe I'm ready to knock this thing out of the park. Any advice or links to videos/pictures? Thanks guys. I'm finally starting to believe I'm going to be getting this done. :)

    The guides that Mamu posted really helped me out.
    In regards to the 4 prongs, you only need one side, you can clip the other side. I verified by putting a continuity gauge on it.
    The heat shrink on the prongs only need to be long enough to butt up to the tac switch and cover the unshielded part of the wire. if you end up with it too long it'll be alright. As i said in my build thread, ensure you don't bend the tac switch prongs once wired until you know exactly where you want them, they get a little frail.
    To soldier the wire to the prongs, get a little soldier on the prong and hit the wire with a little soldier and make sure it soaks into the wire. Then just lay the wire on the prong and hold the iron on it until the prong and wire have merged. pull the iron away and let the soldier cool then verify you have a strong joint by giving it a little tug. don't forget to put your heat shrink on the wire before you Soldier!!!

    There is a great guide that mamu posted about fuses, it's in the battery mod thread as well and is typically on the first couple pages.

    Good luck!!
