I own a 2002 RX300 and installed an after market tow light cable. Come to find out after installing the fuse for the tow lights, that the connector on the RX300 was not active. I called the dealer and they explained that they would check it out for $90, b/c it was installed after market. Does anyone know if there is another connector or fuse to enable the tow light plug on the 2002 RX300?
