For those considering to fit a towing bar :
Behind the left rear lamp (has to be taken out) is a multiple connector (seven pins) for the electrical connection. It is taped to prevent the ingress of dirt. If you have the original Jaguar harness for the towing bar, it plugs right in. Standard 'bullet' connectors can be used instead to make your own wiring harness.
