If you have a v1, go with the wired install. With how short the wires are, you could just hack apart an old hard drive cable. I recommend the 80 pin cables because they only have a single copper stand (just makes it easier for n00bs to soldering). Soldering is very easy. You are going to want to use a 15 watt soldering iron (if you wanna be fancy you could buy a 12 watt pencil iron) because it's cheap, won't get too hot... well it does get 800F..... You will also want to use some rosin. Both the 15watt iron and rosin can be bought at radioshack for under $20 if you need to buy them.
First, you are going to tin the iron:
1. Get it nice a hot.
2. apply solder liberally (don't be a dumbass and have it dripping everywhere

)
3. Get a good portion paper towel, at least a few layers thick. Soak it in water and wring it out.
4. Use the wet paper towel to wipe the excess solder off of the iron
You do this because it makes the solder flow MUCH more easily off of the iron, and you won't need anywhere near as much solder.
If you have multistranded wire you are going to need to tin the wire if it already isn't done:
1. Twist the wire so it is all in one nice bunch.
2. Apply some rosin to the wire (if you have the paste just dunk the exposed wire in it.
3. Now take your freshly tinned iron, apply a very small amount of solder to it (just touch it lightly to the solder to get a little) and apply the soldering iron's tip to the exposed wire.
4. repeat as necessary.
Now that you iron is tinned and all your wires are tinned you are ready to solder.
1. Apply a small amount of rosin to the point you are soldering to. Too much IS a bad thing. Some will say it isn't but too much will make the solder roll off if the rosin is boiling. Don't be too paranoid, though. You'd have to have A LOT for that to happen. Just take a toothpic, thumbtack or whatnot and dip it in the rosin. Then touch the tip to the point and you have enough.
2. Place the wire on the point you are soldering to. Don't be a pansy about this..... keep your finger as close as possible to the point to hold the wire down. We don't want it moving about.
3. Time to solder.... With a small amount of solder on the iron (just touch the iron to the solder lightly) touch the tip of the iron to the point. Don't leave the iron in place for more than 2 seconds at most, but don't count out 2 seconds in your head either. Just get the iron in and out as fast as possible (usually for me I just tap the iron on the point and it's soldered on electronics). The wire SHOULD attach easily. If not you either have too much or too little rosin.
The above will work great for the v1. A special note about that d0 point. It will help if you tin that point first. Just put some rosin on that bare point and apply a little solder to it before you solder it. That will make it much much easier.
I'd add a guide to fill in those points on the other versions, but it'd be a waste of time...... just use the pin header.
Hope this helps you out.
