PROBLEM - Fitting Westfaliia Dedicated electrics to Audi A4 B8 2015

[Carl Robinson]

Really need help with this.

I bought a tow bar and Westfalia dedicated electrics for my 2015 Audi A4 Avant S-Line B8 (Definitely 2015 model not B9 2016 model). Tow bar was an absolute dodle to fit. Took about an 90 minutes to fit.
The dedicated electrics are another story. The destructions say.
Installation Instructions
Remove the rear cover on the black fuse box (fig. 1/5) and open the purple catch. Insert the following wires in the respective fuse chambers: -
Red wire into chamber 2 A.
Red/blue wire into chamber 3 A.
Red/black wire into chamber 4 A.
Problem is that the car doesn’t appear to have the fuses labelled A (See photo below) The other fuses shown on the diagram below can be seen, so where do Red, Red/Blue and Red/Black wires connect?
Perhaps chamber 2,3 and 4 refer to the fuses in position B (See photo).
21. Close the purple catch on the fuse box and replace the black cover.
22. Insert 15 A fuse provided into fuse position 2.
23. Insert the 20 A fuses provided into fuse positions 3 and 4.

Only for A4 Avant: Unclip the red fuse carrier (Fig. 1/6) from the bracket and detach the black cover. Open the violet locking mechanism by sliding it
Problem 2,- I don’t have a Red fuse carrier
28. Lift off the violet frame and remove the 15 A fuse from fuse position 8.
29. Release the black/red cable from the fused side of the fuse chamber 8 A and insert it into the 1-pin housing on the cable set.
30. Insert the black/red conductor (within the 12-conductor cable set) into the fused side of the fuse chamber 8 A.
31. Now close up the open 1-pin housing.
32. Close the violet locking mechanism on the fuse carrier, press on the black cover and clip the fuse carrier back into the bracket.
33. Re-insert the 15 A fuse into fuse position 8 and snap the violet frame back into place.

Really hope someone can help
