Is it the socket / connector for the tow bar?
Hi
could you tell me if this is the socket for the tow bar electrical? I'm looking to install a tow bar on my C5 and I've found this socket in a sort of "hidden compartment" on the inner left side of the luggage compartment (please be aware that it is a left hand drive vehicle). I really hope that it's this socket, if not (this is the place for a disappointed emoji), please tell me what is this socket for and more important, where I can find the actual socket.
Thanx.
Avi

Re: Is it the socket / connector for the tow bar?
Towbara and the electrical harness AND the trailer fuse box unit are separate items Avi.
2 things to consider. There are manufacturer-specific electrical kid and generic third party units. The manufacturer approved units are designed to interface with the car’s stability control system (ESP) so that it knows when you are towing and can adapt the road holding programme to take towing trainers or caravans into consideration.
There is a special trailer fuse box and relay unit available that fits into the rear left compartment on a saloon, where the plugs are there ready, the wiring harness then plugs into this unit. The trailer unit then talks to the BSI and to the ESP ECU whenever the electrics are plugged into the unit. It also provides proper fusing for the trailer lights for example.
There are several approved tow bars available depending on mcwhicle model. If you want these I can supply you with them.
Unfortunately that picture won’t help and could be anything.

Re: Is it the socket / connector for the tow bar?
These are the Cirtoen Approved parts for your specific C5 Avi:
Note: In the table, I have included the Trailer Relay Unit and the 13 pin socket separately - however if buying the electrical harness kit (9428F7) - these are BOTH included in that kit!
Electrical Harness:
Vehicle -Specific Fuse Box and Supplies, Part 9688EL | Electrical Harness Part 9428F7 |
13 Pin Socket Part 1609119280 | 9427EA Tow Bar that can be removed without tools |
9427CZ Tow Bar with Tow Ball that can be removed without tools | 9427CY Manual Retractable Tow Bar (needs Tools to Remove) |
9427CX Swan's Neck Towing Ball | 9427CW Manual Retractable Towbar |
Blank | |
9427CV Swan's Neck Towing Ball (Removable Neck) | Blank |
Note: In the table, I have included the Trailer Relay Unit and the 13 pin socket separately - however if buying the electrical harness kit (9428F7) - these are BOTH included in that kit!
Electrical Harness:
- This harness is particularly suitable for providing the lighting supply to trailers or cycle-carriers on tow bars.
- This harness has been developed to incorporate all of the vehicle special features.
- It also provides an electrical supply to the fog lights and reversing lights.
- Comes with a 13-way socket to correspond to the trailer socket.
- It incorporates all the features needed for good compatibility with this vehicle and is SAFE, RELIABLE and EASY to fit.
- The functionality of the harness will be obtained by configuration of the BSI (fitting by the network is imperative).

You've wrote that there are plugs in the rear left compartment. these are exactly what I'm looking for. the towbar kit that I've ordered (haven't received it yet) includes an interface to the vehicles system that plugs into those plugs. as I've mentioned before, I've looked into the luggage compartment and removed the "cover" that allows access to the rear left tail lamp and that socket was all I've found. could you give me some hint where these plugs might by?

Re: Is it the socket / connector for the tow bar?
Avi - have a look at this post - Elis was looking to wire in hi amplifier on his X7 saloon and clearly shows a picture of the inside left boot area. That looks like the brown plug you are asking about and as I think I answered in that post it should be the under inflation detection unit connectors.

Re: Is it the socket / connector for the tow bar?
On the Tourer the connectors are definitely on the LH side but I think the Saloon might have them on the RH side so I assume that your car is an Tourer. I fitted a Westfalia tow bar and manufacturers electrics on to my Tourer last year. The electrics actually work the lights on a tow board without activating the BSI but, of course, you won't get all the clever bits like modifying the ABS and reversing sensors.

Re: Is it the socket / connector for the tow bar?
Hi
Since I wasn't able to find any connector besides the one that it's pic's I've posted and taking into consideration the difficulties to find the components that were suggested by Marc (even though I'm sure it's a better solution), I've seen that there is some "compromise solution" that called "bypass relay" that to my understanding is some sort of relays that connects to the various lights so that they won't load the ECU by connecting additional load caused by the trailer light bulbs. the draw back of this solution are at least two - they don't "talk" and tell the BSI that there is a trailer involved (I hope that in my case it's not so dramatic, since I'm not towing a caravan, only quite a small luggage trailer that is limited to 500kg - ca. 1000lbs.). the second problem is that this bypass relay needs constant supply of +12V and unless you can tell me if I can find an already existing point of +12v in the luggage compartment - a wire (fused, of course) has to be drawn from the battery to the luggage compartment. if this option was used, please share your experience with me.
Thanx.
Avi

Have you looked on the opposite side (RH side) above and behind the wheel arch?

No. I took it for granted that it should be on the left side. I'll check it.

Re: Is it the socket / connector for the tow bar?
This is what I've found on the right side. did I hit gold?
The black wire on the left of the connector is not connected. just a short wire.
