INSTALLATION GUIDE

1. Remove the instrument panel.
2. First, connect the MALE connector. An LED on the device (look at the seam of heat-shrink tubing) should light up for 5-10 seconds.
3. Next, connect the FEMALE connector (the instrument panel should turn on).
4. Check operation of the device. Conduct a test-drive if necessary. 
5. Install the instrument panel back. 

TROUBLESHOOTING: On most car models, both connectors, male and female, can be connected both ways. Hence, most of the troubleshooting is done by simply reconnecting the device. Thus, if you you don’t get an LED light on the device: flip the male connector 180 degrees / if the instrument panel does not light up after connecting the device: flip the female connector 180 degrees.  

Please note, if the device is connected incorrectly, it will not cause any damage to the car's electronic system.

ACTIVATION

Press and hold the "BC" button on the left lever from the steering wheel for 5 seconds.

Usually Mode 1 (see below) is activated by default immediately after installation. Thus, there is no need to activate the device. Successful mode switching is confirmed by hazard lights indication on the instrument panel. Modes are switched successively (one after another).
