The Towbar prep socket is normally taped to the inside of the body panel near the EHU/Water filler.
Access via the rear wardrobe gas/water tank or via the rear leisure battery storage area.

Not certain but I believe that it also needs to be programmed in so not just a plug and play job.

No problem for that, the local dealer will do it. I just want to find the socket, if i ja e to unmount something, i want to do it myself

I've been told that if you have the Factory Towbar Prep then the relevant programming has been done from the factory.

Hi everyone,
I’m trying to clarify a few things regarding towbar installation on my 2024 VW California T6.1 with factory preparation 1D7, and I would really appreciate feedback from those who have actually done this installation.

Here’s my situation:

I checked with a VW dealer using my VIN and confirmed that my vehicle is equipped with 1D7 (towbar preparation).

However, I have inspected under the passenger seat and I did not find any obvious control module or dedicated towbar wiring, which adds to my confusion.

The correct electrical kit for my vehicle should be 7LA055204A (confirmed by VW), and I also received the official installation instructions.

This is where things get confusing:

• One installer told me that nothing inside the vehicle needs to be removed, and that the wiring is routed externally under the vehicle, using existing factory provisions.
• Another installer claimed that the wiring must be routed from the front to the rear through the interior, requiring removal of seats, trim panels, etc.

In the official installation manual, there are indeed quite invasive steps (removing seats, accessing BCM, interior disassembly), which seem more like a full retrofit scenario, not a vehicle with factory preparation.

My questions for those with real experience:

1. With 1D7, does the towbar wiring already reach the rear of the vehicle, or does it stop in the front area (e.g. under the seat)?
2. Is the correct installation supposed to use an external routing under the vehicle, without dismantling the California interior?
3. Are the invasive steps in the manual just generic instructions covering multiple configurations, or were they actually required in your case?
4. How invasive was the installation on your vehicle in practice?

I’m trying to understand the correct procedure to avoid unnecessary disassembly on a fairly complex and sensitive vehicle like the California.
Any real-world experience would be extremely helpful.

Thanks in advance!
Francesco
