emission light

There's an box under the dash that you can reset, or just unplug. It's just a reminder light set to come on after a certain amount of run time, usually around 60000 miles to tell you to check the emissions equipment. The Haynes manual shows a picture of it and describes how to reset it. It won't throw codes, because it is completely independent of the engine computer. It won't hurt anything to just unplug it either. It's under the dash, somewhere above the gas pedal - it's a small black box. I don't think disconnecting the battery would have any effect, but I could be wrong.
