I am trying to wire up parking sensors to my 308.
There is a mult block connected to the rear LHL with a number of different colour wires.I have connect the red positive wire from the sensors to red on back of block and the black negative from sensors to yellow with green stripe on block, but they do not work.
I cannot connect right up to the reversing light as it is powered from the circuit board.
Can you help. Thanks.
all you need is a test lamp...remove connector place in reverse with the ignition on and just touch each terminal till the test light illuminates..there is the supply for reverse light connect to that and a good earth and job done
