i just bought a Rexing V3 a week ago and i already used it for 6 hours traveling using the included cigarette's lighter cable and i don't have a problem at all, it works perfectly. i ordered a smart hardwire kit because i want to have a parking mode feature. but when i got the hardwire kit i went on to install it following the instructions video from rexing. the red wire goes to switched or on & off fuse, the yellow wire goes to hot or always powered fuse, and the black wire goes to the bolt for ground. i used a fuse tester to determine which is the right fuse for each wire. the problem was when i was done connecting all those wires, the camera started turning on even my car engine still off. i left it like that for awhile to observe it that it might turn off in a few seconds, but unfortunately nothing happened, the camera still on. but i still went on trying to enable the parking mode and its not working also. i also tried disconnecting the yellow wire and leave the red and black wire connected to see if it will work normally without the parking mode feature but the camera turned off when i disconnected the yellow wire. i tried so many ways, searching videos on how to trouble shoot it and accidentally i was able to work it in the right way by reversing the yellow & red wires. the camera will start when you start the engine and it will turn off by turning the engine off but the problem is the parking mode still not working. i don't know if its the hardwire kit is the problem/defective or something else. hope someone could help me.
