BiXenon H4 headlight connector wiring colours

[magpies]

Hi
I have purchased a H4 BiXenon kit and the connector from the relay/harness controller to fit onto the car headlight power connector is not only a different shape but also completely different wire colours.

The car headlight wires are:
Black = earth
Yellow = dip beam
red = main beam

The BiXenen connector (goes to the relay/harness controller) wires are:
Left = white
Centre = brown
Right = blue
which of these do I connect to the car wires?

I don't want to connect anything until I know which is the earth then I can sort out dip/main without blowing any electronics.

any ideas?

Sorry - thought I had given enough - car is a Freelander and it is an aftermarket type

can dig them out and give make/model if need be
