Retrofitting towbar, wire connecting question!!!

[henri43]

Hi,

I have purchased towbar from another car and want to put in to my car.
Towbar came with wires, control unit and of course with towbar itself.
I am so far that i know where to connect wires from towbar module (red connector).
From red connector roes 5 wires to that blue connector in fuse box module, pin 1, 17, 19, 20 and 21.

How should i connect the wires?
Should i remove existing wires from blue connector and replace with wires what are coming from red connector?
Or should i join existing wires and red connector wires?

Thanks a lot

Get yourself elsawin or download the schematic from Erwin online, wire it exactly as factory states as it's a fair current & don't piggyback onto unknown systems, I remember fitting one to a C6 years ago, that was fun.
