Tow bar success?

[veebee]

I became interested in the Forum because I needed to fit a tow bar to my newly acquired 52-plated M59. I had already pre-wired the electrics to a connector block, behind the LH rear trim panel, using the permanent live feed to the rear wiper motor to power the by-pass relay and trailer indicators. I ordered a Titan tow-bar (£63.40), from PF Jones, during Tuesday lunch time; it arrived Thursday complete with ball, cover and 12N electrics (socket, fixing plate, cable & buzzer). I reversed the vehicle onto some bricks and, lying on a bit of old hardboard, was able to fit the bar reasonably easily (only banging my head once, which is pretty good for me). The 7-core went up through a convenient grommet below the back of the lamp cluster and connected to my block. The buzzer was inserted in the block wiring and, hey-presto, I probably saved myself couple of hundred quid.
Now what shall I tow?
