If you're trying to put some buttons on your steering wheel, the wireless systems by Cartek Motorsport Electronics are by far the best solution. No more curly cords that always get in the way. Instead, the programmable systems by Cartek allow you to configure up to 8 buttons to do what you like and the connection to the car is wireless.The systems work via an ultra-fast infrared connection, so fast in fact that Cartek came up with a version with paddle shifters to control sequential or DSG gearboxes. The receiver module can be wired into any ECU, dash, PDM or other electronics module and each channel can be configured to behave in any of 6 ways. Whether you need flashing, latching or momentary, the Cartek receiver module can make any button perform just the way you need. Typical battery life on the steering wheel is 3 years and rest assured, there's a battery test functionality to check the charge.For a limited time, we are able to offer the standard CK-WS-09 version for $679 instead of $829.95 and the paddle-shift CK-WX-07 version for $1149 instead of $1399.95.
