Thread: Towing, which socket to use?

The right hand socket (should be black) has been wired for Oz. The white socket is apparently a European thing. I had the white socket removed and replaced it with an Anderson Plug and heavy cable from the second battery to run power for the caravan battery. Done by the local auto elec used by the local dealer. Both he and I were concerned at the relatively thin power cables running to the white plug (there were two from memory) and the very thin pins in the loom connectors back inside the car for this socket. the current set up has been working a treat since new over three years ago.

I have a follow-up to this thread. Ive recently purchased a RRS, I also have 2 plugs at the back. I have a boat with Hydrastar braking system. Ive purchased a P3 from Tekonsha which has been already installed. However, the dealer service is saying that they are going to take power from the white plug and then create a harness to combine this power with the trailer plug, which includes the P3 signal. Is this the only way of doing it?
