Hello everybody, I want to buy an scan tool and I need to know what computer is in my truck? OBD or OBD2. My truck in a 1994 s10 4.3l z 4x4. Thanks Mark

Should be the earlier OBD1 type with the rectangular diagnostic connector. A good scanner for the money is the AutoXray job, but I'd suggest getting the more expensive one that will work on the newer models too, someday you'll need it.
