Installing a wireless back-up camera

Help - my husband got me a wireless back-up camera for Christmas. Now to install it. It says I need to locate the reverse light circuit to connected. I am not to familiar with wiring on a newer model car. My area of expertise in wiring comes from a 71 Ford F-100 and a 66 Ford Mustang.

I haven't been able to locate a wiring diagram so I can be sure where they are.

Anyone have an idea?

 

ok, it is easy
I go take a few photo, and post it here, make it easy

 

I actually got it. It was easier than I thought it would be. Trick was finding a place to put the wireless transmitter, but I found a good place to put it.

 

ok, i do took some photos, but just did not have time to upload it, due to have to clean up my kid old toys
Happy to know you find the way to install it. How the wireless back up camera work?
