Hey guys.....my 93 sierra build is finally done(or close enough) and it's week three of daily driving it. My check engine light is on and at first I didn't care bc it's a 93, doesn't matter for nys inspection. But now it's driving me nuts.........I can't help but notice that the obd connector looks compatible with obd2 tools.....it should likely be obd1 given its a '93 though......can I use my obd 2 scan tool? How do I shut this bright annoying light off?? Thanks in advance!
