Done a fair bit of googling and think i know the answer but wanted to check with other on the forum first. I'm fitting a towbar to my 530D E60 before purchasing the OEM electrics @£110 notes was trying to see if a universal relay bypass is a cheaper option. Dont want to penny save for the sake of it but think over hundred pound for a cable is a rip off but if this counters issues further down the line then I will cough up. Appreciate the wisdom and knowledge from all
