I have a 2014 BMW X5 with factory-fitted towbar. It does not have a fridge relay to run the fridge on 12V whilst towing. BMW and my local towbar specialist (Tow-Rite) say one cannot be fitted because the car's wiring loom is not designed to take it, others tell me it can be done at great expense by replacing part of the loom (so must be done by a BMW specialist), still others say it is possible to cut off the BMW supply to the 13-pin socket and start again (although I fear this might mess up the car's computer controls, including the camera which focuses on the tow-hitch when reversing with the towbar out). Do members have any advice?
