Hi Christopher,

Thanks for your question. This is one that we have not yet covered.  

The WiTi product is a relative newcomer to the market and as such, I have not seen a lot of commentary about its interoperability with trailer brakes. However, after digesting their product information and our intimate knowledge of sway systems such as the ESC and BMPRO SwayControl, happy to share the following.

The ESC system has been designed to take power from the towing vehicle and it is recommended that you wire appropriately through a 12-pin plug or via a separate 2-pin Anderson connection.  Here, best practice suggested that constant power is supplied from the tow vehicle. In comparison, the BMPRO SwayControl is designed to maximise the opportunity to utilise the caravan house battery. There are benefits and pitfalls to both.

The ESC system from ALKO is suitable where there is no battery in the caravan, using the power from the towing vehicle. The downfall to this system (in my experience) is that you need to ensure that your connections from the towing vehicle are well maintained and in “tip-top” working conditions otherwise you can experience the ESC cutting in and out when it is required without the driver having any knowledge of this actually happening.

The BMPRO SwayControl on the other hand enables you to utilise the house battery in your caravan and is powered directly by this battery. So, you will need to ensure that not only is there a battery onboard but that it is maintained and charged to a level that can provide the adequate power requirements.
