This 13 pin Trail-Tec wiring kit is made specifically for your AUDI A4 B8. This 13-pin electrical kit connects to the existing data bus system in your AUDI A4 B8 . Faulty trailer lights will be indicated by the car's own system. After installation of this electrical kit, the car needs to be coded for trailer use.
A shutdown of the factory-installed parking assist function of your AUDI A4 B8 is supported by this 13 pin CAN-bus module electrical kit. Included in this kit: high-quality, vehicle-specific colour-coded plug connectors, custom cable lengths and a detailed AUDI A4 B8 installation manual. This electrical kit is installed in the boot only. A continuous current connection (terminal 30) for the trailer control unit must be available in the rear of the vehicle. No drilling in the rear panel of the vehicle. A grommet is already present on your AUDI A4 B8. It is used by this vehicle-specific 13 pin kit. It's not required to connect each cable to a trailer socket. A socket is already connected with this kit.
Extend pin 9 of the trailer socket to steady plus to power electric items in the trailer with the 107650 with steady-plus function. Or you can use pin 9 for steady plus and pin 10 to charge a second battery in the trailer. A combinet retrofit solution for steady plus and charge 139243 is available separately.
Read and follow the instructions provided by AUDI concerning the installation of a Trail-Tec wire kit.
- this wiring harness kit was developed for vehicles with no pre-equipment, but can also be used on vehicles with the 12-pin connector
- it is possible that the engine cooling system of the vehicle is not equipped for operation of a trailer; in such cases it may be necessary to replace parts of the cooling system (e.g. fans)
- we will be happy to to help you check whether your vehicle is adequately equipped. Please contact us and have your chassis number on hand
- if the vehicle is pre-equipped for the AHK, there will be an open 12-pin connector (in the boot behind the right-hand side panel)
- Trailer Hitch: for vehicles without towbar preparation
Installation instructions are given here in different languages and, depending upon the product, complementary installation help and additional images which make the installation or attachment of the product easier for you.
