Hi FJR PILOT. I think your assumption is probably right. The Jag 'plug and play' tow bar electrical kit has been unavailable for some time. I think some installers shy away from the S-type because of its complex electrical system with switched earths rather than switched positives. I had a Witter tow bar fitted two years ago, and the installer had no problem making a twin electric system using stock items.
As for the ugly tow bar, if you are willing to pay, a detatchable is the answer. Mine is a standard fixed affair, but it saved my bumper when the old boy next door ran into my car while he was attempting to park his brand new Astra. I just had to pull the bracket holding the electrics straight, he needed a new bumper!
