Yeah, you could run it under the car but I didn't want to drill any more holes than I had to. Honestly, you don't have to pull out anywhere near the amount of stuff I did. I actually pulled out more than I had to because it was the first time I pulled my car apart. With more experience now the only thing you really have to do is undo the two clips to fold the rear seat back down. The rest you can just tuck the wire under the panels.

when i shift into reverse nothing happens the only thing i see is a light in the morror starts flashing? What does this mean? Did I do something wrong its almost like the camera doesnt have power....Help!

What harness did you use?

The one from ofer

Are you getting power and ground to it?

what exactly does that mean?

It means: is the harness properly grounded?
