Bike rack Light board

[woodypk]

Hi guys,

I made myself a 2 bike bike carrier for the '2 and I need to wire up a trailer light board since when I have two bikes on the lights are obscured.

Does anyone have a wiring diagram or even already know what colour wires are the live wires for the tail lights and indicators?
I don't want to have to buy a multimeter if I can help it.

cheers guys

Tom
