Question:
I am looking for a trailer wiring connection that goes from an EU 7 pin female connection to a standard RV trailer connection. The EU seven pin fits a wireless trail light system that I need to hook up to my Toyota Tocoma with a towing package.

Hello David, thanks for reaching out. I do have a solution for you, but we do not have an adapter for a European style 7-way to a standard RV 7-way. What I would do is simply replace the EU 7-way with a standard RV 7-way. It should be pretty easy to re-wire using a plug like the Hopkins # H20042. I have included a wiring diagram for your reference.

Hey David, did replacing the EU 7-way with a standard RV 7-way work out for your wireless trail light system? I'm asking because your experience could help others in a similar situation.
