I own a 94 Land Cruise so it's pre OBDII. A friend of mine gave me a used Snap On MT2500 scanner that he said you can use to check pre OBDII engine codes with, he said it works on cars from 1980 till 2009. It came with a bunch of connectors and software to hook it up to different cars. I checked and yes it has the connector and software to hook it up to my truck. Problem for me is it came with no books telling me how to use it. Snap On stopped supporting this scanner in 2009 so i can't get the books from them. I checked Ebay, and see that there is a ton of stuff still available for it. So my question is this, have any of you used this scanner, and do you think it's worth spending money on?
