I'm wanting to do some computer data display, but so far I've had major troubles building my own cable (i.e., the circut is perfect, but no data comes through). I would like to try a professionally built cable, but I want to make sure it will work before I buy it - so if someone who has one would let me just plug it in and see it work with my car, I'd order one online.
Of course, if someone has one they want to sell...

I'm also taking suggestions for a mechanic that has worked with Camaros in the Portland area...

Thanks
