Firstly, excuse me but I'm spanish and don't speak (write) english so good.
I found this forum at www.clubopelastra.com (spanish club).
I bought a bike-carrier for back-door. The Thüle Freeway 968, and the lightboard Thüle 976.
I tried to fit them, but the lightboard needs the trailer plug.
Is there any electrical diagram or for fitting the trailer plug?
I'm afraid to not driving legally without the lightboard.
