Aux 12V rear socket

[dejancurk]

Hi,

I have a Connect combi-van dec 2018 (2019 facelift) with 5 seats. Short wheel base. I have a 12V socket behind the middle console but not in the trunk.
There's a hole for it, but I can't find the electrical connector. A lot of guys have orange/brown connector for 12V aux socket, but doesn't have it. Is this normal? Can I connect/splice other wires for 12V connection? What would you guys recommend?
