B7 2014 Passat OE retractable electric towbar

Post by chisel_chops »

Hi,
I have a Westfalia electric retractable towbar 3AA 803 880H, control module part number 7N0 907 383 and release switch from a 2014 B7 Passat estate.
I would like to fit it to my 2014 B7 Passat estate TDi BMT 140ps.
The wiring for the 13pin towbar to 16pin black connector for the control module is complete, there is a separate yellow/red wire with a single connector, this is connected to pin10 on the towbar.


The red connector has the following wires coming out of it, all 300m long, as this is where the wiring loom was cut.
Pin 2 black/blue wire
Pin 3 back/red wire
Pin 5 green/white wire
Pin 7 orange/green wire
Pin 8 orange/brown wire
Pin 9 purple/red wire
Pin 10 brown wire
Pin 11 grey/yellow wire
Pin 12 white/red wire
There is a separate yellow/red wire with a single black connector that fits the trailer loom connection.


And on the blue block
Pin 11 brown/black wire
Pin 10 red/yellow wire
Pin 6 brown/white wire
Pin 5 white/green wire
Pin 4 black/green wire

Release switch
Pin 1 brown/white wire
Pin 2 white/green wire
Pin 3 brown/black wire
Pin 4 black/green wire
I'm sure the above connect to the same colours in the blue connector block.
Can anyone help me with the location of all the wires to the correct location in the fuse board/canbus?
Is this even possible?

Hope someone can please help?
Many thanks,

Chisel.
