Dethleffs must be the same wiring as Hymer

[Bustup15]

I have seen threads quoting Hymer wiring colours but don't remember seeing the same about Dethleffs.

Installed additional wiring directly off an existing Wago connector with spare outputs. Core colours blue and brown, negative and positive?

No way, blue is positive and brown negative, new USB socket not working, checked my connections 3 times before I got the meter out ????, reversed the connection and all is well.

They are under the Hymer group so a possibility they're the same.

Standard German 12v wiring is blue positive, brown negative. UK standard 12v wiring used to be (not looked for 20 years) blue positive, white negative.

Blue not necessarily +ve but certainly Brown is -ve (often marked on terminals as 31)
