Oh thats cool. Ive already got my stuff on order but I might just try one of those too. Of course I could just take a pc board and solder some pins in the right places to make something similar.

I was thinking of doing something similar, using a piece of hard drive cable to connect parts. Ive been thinking about making a 2 piece setup for cleaner installation in my dashes which have limited real estate. One half would have the display and switches in a small clean enclosure, with a hard drive connector. That would mount on the dash, one custom matched to each car. The other half would have the Freeduino and all the rest of the parts on a PC board in just whatever type of enclosure, with a hard drive connector, and it could be tucked in behind the dash. And of course the two would be connected with a neat looking hard drive cable. Or something different if I have interference problems or anything.

Then I can take the mpguino out, either to reprogram it, or to swap between vehicles. And keep the display unit in place already made for each dash.
