I got it off China Aliexpress for about USD$79.85. Problem is they don't come with an instruction manual. Initially contacted the seller, didn't really gave me a proper instruction for installation. Hence decided to ask if anyone here have done it before. They just got it back to me, and told me to connect 3 out of 6 wires, 3 being battery both positive and negative and to ACC fuse, which I believe its the driver side fusebox. Haven't had the time to tried it, but will give it a shot tonight if I had the time.
