CARM INTERNATIONAL TOWING
Years ago, installers simply “piggy backed” the trailer lights onto the rear vehicle lights. The vehicle wires were thick & generally could take the extra current without any problems.
These days, vehicle looms are engineered to carry just the required current. This saves on manufacturing costs & vehicle weight. In addition, many vehicle management systems detect any increased current loadings. Should any anomalies be detected, the engine management light will come on & many late model vehicles will then shut some systems down to protect against overload conditions.
To overcome this, towing adaptor modules are fitted in the vehicle’s boot. The inputs of these modules are connected to the various lights at the rear of the vehicle “tapping off just a very small current” to detect which lights are on. The module then switches the heavy load through heavy duty automotive relays from the battery to the trailer lights via the trailer power socket.
There are four 12 Volt models & three 24 volt models in the Towing Adaptor range. Simply select the chosen module below & install with the generic looms supplied. The internal electronics has been designed to be “virtually invisible” to the vehicle’s ECU. This ensures you can install these towing adaptors on almost every vehicle sold today.
TA200-12V-P & TA200-24V-P
Will operate with most vehicles. Use with trailer that runs either filament bulbs or LED lights & where vehicle runs filament bulbs. 12 Volt, 25 Amp (or 24 Volt, 15 Amp) Trailer Towing Module designed for newer vehicles that do test for blown brake & tail lights and vehicles that will detect any extra load being applied to the rear brakes, indicators, tail lights or stop lights. LEDs light very quickly & the “P” module contains specialised electronics to “hold out the fast test pulses” that are sent by the engine management system when testing for blown bulbs.
TA200-12V & TA200-24V
Always use when both trailer & vehicle run LED lights. 12 Volt, 25 Amp (or 24 Volt, 15 Amp) Trailer Towing Module designed for newer vehicles that will detect any extra load being applied to the rear brakes, indicators, tail lights or stop lights.
TA100-12V & TA100-24V
For older vehicles where trailer & vehicle both run filament bulbs. 12 Volt, 25 Amp (or 24 Volt, 15 Amp) Trailer Towing Module designed for older vehicles that do not test for blown brake or tail lights and do not detect a small increase in the load being applied to the rear brakes, indicators, tail lights or stop lights.

REMEMBER: All TA200 modules have a high internal input resistance of 15,200 ohms. This ensures that no damage will occur when connected to the vehicle's electrics & that the vehicle's ECU will not detect the module. This feature is critical to the sales success of these electronic towbar modules.
Some vehicles like the 2009 (or later) Holden Astra have a single rear bulb that glows dully for a tail light & brightly for a brake light. Due to the special design features of the Towing Module TA200-12V-P347, this model can be connected to these vehicles. Please advise us that you will be installing it to a 2009 (or later) Holden Astra. We will provide you some helpful instructions to make installation a breeze.
The Voltswagon Amarok pulse width modulates (PWM) their rear incandescent bulbs. Again, due to the special design features of the TA200-12V-P347 Towing Module, this model can be connected to these vehicles. Please advise us that you will be installing it to a 2009 (or later) Holden Astra. We will provide you some helpful instructions to make installation a breeze.
For the BMW X5 (all early to late models) please order the Towing Module TA200-12V-P347 model. Please advise us that you will be installing it to a BMW X5. We will provide you some helpful instructions to make installation a breeze.
The Audi Quattro 4WD 2002 onwards should have the TA200-12V-P347 towing module installed. The Quattro 2002 (& later) run a single bulb with 2 seperate filaments (for the tail light & the brake light).
A Towing Module to suit the Mercedes ML350 4WD 2010 (& later) will be available in the first week of May 2013. The part number is TA200-12V-P347-M. The rear lights of the ML350 are LEDs.
