Darek Posted July 18, 2012 Share Posted July 18, 2012 My car is equipped with 4 way flat connector for trailer. It has a rectangular shape. But European trailers have round shape connectors with 7 pins. So I want to cut off this connector and attach European version. I am looking for wiring diagram for American connector - which cable has which signal? Link to comment Share on other sites More sharing options...
mluczaj22 Posted July 19, 2012 Share Posted July 19, 2012 (edited) just buy the round one with the 4-way flat end and plug it in to your existing 4-way. green-right signal. brown-tailight. yellow-left signal. white-ground.

theexbrit Posted July 20, 2012 Share Posted July 20, 2012 Here's a good site for trailer wiring, hopefully you can find what you want here.........http://www.hopkinstowingsolutions.com/products/adapters/ I'm sure they'll ship to Europe, if not maybe someone on the forum can help you. Here's another site that has diagrams...... http://www.etrailer.com/faq-wiring.aspx Link to comment Share on other sites More sharing options...

theexbrit Posted July 21, 2012 Share Posted July 21, 2012 The 7 pin seems to be for big trailers with brakes, etc. If (like me) you just tow smaller trailers, the 4 flat should be fine. Link to comment Share on other sites More sharing options...
