I have a 95 TA and I have TTS Datamaster. They told me when I got it that my computer is an obdI but I need a obdII cable. I can't get it to work. I plug it in and the check engine light come on and stays on and the fan stays on the entire time, but I can't get any readings on it. Please help. I need to see what is going on

 

yeah you do have an obd 1 computer just the connector is different go to www.mastach.com and click on connectors and it will show you what pins to plug into to pull data
