I cut up a few paperclips, into pieces about 1/2 inch long or so, to use as pins. They fit pretty snug in the headers, so they dont move sideways and dont take a chance shorting against the adjacent pin. Then I just soldered my wires to those. For the wires themselves I just used network cable. A 5 ft cable from the dollar store goes a LONG way.
On my first guino, I built the extra components into a small section of perfboard along with the tact switches. On the 2nd one, I used a scavenged board with tact switches which was a perfect fit. So for the rest of the components, rather than do another perfboard, I just built the components right between the pins on the Freeduino board. I posted a pic a little earlier in the thread. Seems to work great so far.
Just my preference, I wont use splice taps anymore. I used to swear by them, now I swear at them. If they dont turn green and corrode, theyll loosen up over time. I lost my trailer brakes from them loosening. Anymore I just strip and solder and tape everything.

I ended up getting different switches, since I want to mount mine permanently in my car. I'm going to have just the LCD showing and the switches mounted just below coming through the plastic. They are part number 275-0644, rated 3 amps at 125v ac or 1.5 amps at 250v ac. I know it's a 12vdc circuit, but I can't see any reason why I couldn't use them. Does anybody know any reason why not? RS is only 1 mile away, so returning them isn't a problem.

Good luck with those switches, hope they work out for you. I used one of them when I relocated my reset button. It seems to work ok. Quite a few years ago I used two of them to raise and lower the air suspension on my car, mounted them in the dash. They worked ok for a little while but then got to where I had to really force them to get a connection out of them. Maybe they make them better now.
