Which module should I choose if I want to carry a bike carrier on the tailgate?

When fitting a bike rack to the tailgate, we suggest choosing an 8 pin wiring kits due to the requirement to carry the reversing light signal. In the case of our products, this will be:

   - basic harness WH1R-G8 
   - advanced harness WH3Q-S-G8
   - tailor made WH1R-G8-RAV4 P2P harness for Toyota RAV4/Highlander and Suzuki Across
   - tailor made CAN-Bus harness MP2S-CAN-G8

*P2P - connecting to existing plugs and sockets in the car's electrical system.

Which module should I choose if I want to carry a caravan on my hook?

In the case of a caravan, the most extensive version of the towbar harness is required. This is due to the need to operate all trailer lights, including the reverse light. In addition, a permanent power supply and charging of the trailer battery is required.

In the case of our products, these will be:

   - MP5-DS-G13 (most extensive module with functionality of ICM-G13 and LED-RGY-500 included)

   - WH3Q-S-G13-ICM (ICM-G13 mandatory in addition, LED-RGY-500 as optional accessory)

Which module should I choose when I want to connect a trailer below 750 kg?

In this case, a basic 7-pin wiring kit is sufficient:

- basic module WH1-PRO-G7

- advanced module WH3Q-S-G7

Note, however, that for such a harness, we will not be able to mount a bicycle rack on the hitch or pull a caravan (among other things, due to the lack of a reverse light or power and charging circuits for the trailer).

I have a car with a 24V installation, can I find a compatible module?

Trailer 24V

Yes, we have a product dedicated to 24V installation - TBM-DB-G8. The trailer must have the same installation voltage as the car.

Trailer 12V

It is also possible to program the module to operate a car with a 24V installation with a 12V trailer - TBM-DB-G8-24/12V. Please highlight the option when purchasing.

Which car models are compatible with CAN harnesses (MP2S-CAN)?

You can find the compatibility list on our website under the link MP2S-CAN Compatibility List.

Can I find PIN 2 PIN wiring kits, if so to which cars?

Below is a list of towbar wiring kits in the "P2P" version. Special advantage of P2P kit is a possibility of connection to the existing plugs and sockets of car's electrical system without cutting.
