IMPORTANT
If you are having difficulties with the installation 
of this 
product, please call our Tech Support line 
at 1-800-253-TECH. Before doing so, look over 
the instructions a second time, and make sure 
the installation was performed exactly as the 
instructions are stated. Please have the vehicle 
apart and ready to perform troubleshooting 
steps before calling. 
When connecting with power cable, please make sure not to mistake the positive and 
negative pole, otherwise the fuse will blow immediately for security protection. If it happens, 
please replace the blown fuse with a new one with same specification, after connecting 
properly to the right pole. Don’t randomly increase the current rating of the fuse, and NEVER 
use metal wire as a substitute.
