Hello All

I am intending to fit a brake controller for towing to my 2010 Tig. The manufacturer of the controller states that the + / - should be connected direct to the battery terminals this I understand. VW have told me that I cannot do this ?? If I do then the car will know that extra powe is being drawn from the battery and will cause a fault.

Can anyone confirm if they have fitted a brake controller this way without any problems.
Or any other accessory for that matter I am sure that there are a lot of guys who would connect power to large amplifiers etc. that would connect this way.
