Have recently had to change my car and had to have a tow bar fitted,the car is a 2.0 l8tr 150hp Ford kuga.The tow bar is a Ford fixed swan neck and 13 pin electrics all fitted by the Ford dealer.The first time I had hitched the van up the car was on auto lights the van lights didn't work turn off auto lights van lights ok,the second thing I noticed was when indicating there was no beep.The question . is this way electrics are now or do I go back to the dealer
