How are the trailer connector cables

Hello gentlemen, I need to know the place where the cables are connected in the 7 -pin trailer plug, but the European need, which is the one that passes the ITV. thank you

Greetings, then I will explain by numbers what is connected to each terminal. I will tell the situation of each cable from the socket that is put in the car next to the ball.

Nº1 left intermittent. (Female, located above, at 12:00)
Nº2 rear fog light. (Female, located at 10:00)
Nº3 mass. (Male, located at 08:00)
Nº4 Intermittent right. (Female, located at 06:00)
Nº5 Light of left position and registration light. (Female, located at 04:00)
Nº6 brake light. (Male, located at 02:00)
Nº7 Der position light, or not used (male, located in the center)

Anyway, if you have a trailer and the installation is well done, you can check the lights with the trailer itself when you have finished connecting all the cables of the car to the zócalo.

All the best.

Ok, you have been helpful, I thank you
