Thanks for the comments guys.......
I guess I was kinda hopping, that it would be simpler to make an adaptor to be able to read the codes on our buick, but it doesn't look like it. I'll just take it in and pay the $25 for the diagnostics and go from there
I'll just keep saving my pennies and keep an eye out for a good used scanner. I'll just can't see spending that kind of moneyright now for a new toy... I mean tool that I don't really need that much...... I'd rather spend the money on our V8 beetle
Talk to you all later and thanks again
