The wire harness isn't complete. I had to splice into the ground wire. And the Illumination wire. And the backup trigger wire. I can't remember exactly, so don't quote me. I had my mulitmeter to help me find the correct wires. I think the illumination wire was the one directly next to the black ground wire. And I think the backup wire was the one 7 over from the ground wire (it's a very light color, not white though). And I spliced the brake wire for the radio into ground so I can play videos.
Overall, this is nice. I've only had the chance to use this about half an hour, but am impressed with the speed it works, and the features on it.
As a bonus, I realized I can change the button colors to anything I want. So now they are purple to match my interior. (Not matching my dash lights though.)
What I like about this camera frame is that it has distance sensors an it and it sounds a tone when objects are detected about 4 feet away.
I pulled the trunk liner out a bit, spliced into the left back-up light, ran the wire though a grommet to the frame. Then I pulled up the left-hand floor board trim and ran the camera wire up to the front of the car and hooked it up to the radio. Since the trigger wire for the back-up exists in the front harness, I didn't have to connect that trigger wire from the light to the front radio. I just have the backup light feeding into the frame to power the sensors.
