Good look. Thanks

I need two things. I have a 1995 Buick LaSabre. This car is OBDI compliant but with a OBDII 16-pin connector. First, I want to know which two pins I need to short to aquire the trouble codes. Second, Where can I find the definitions of what these codes mean? Information greatly appreciated. Thank you in advance!
