Under the front passenger seat is two loose plugs. I cannot find an input for them. There is already one plug in use. I don't know what these others are for. Any ideas? The photos show the loose plugs and the attached plug.
One of the wires is a sensor to determine if someone is sitting in the seat or not so as to make a seat belt warning on the dash go off, as well as for air bags... I don't think Gen2 Prius came with heated seats, but maybe they did in some of them and that's the other wire?
My T-Spirit has the Navigation DVD player under the passenger seat. Perhaps its a connector for that?
