I removed my drivers seat the other day to put in a new one, and I noticed a small grey box underneath it. It had electrical wires going into it and the letters "GJ25 NPSK" etched on it. I have also seen this in another 6 at the junkyard... I looked through the Haynes manual, but could not find it anywhere.. So I was wondering if any of you could inform me what this thing is... really curious about it...
