Where is the Reverse Wire

[TeeUp]

I am trying to install an aftermarket back-up camera. One of the lcd/monitor wires must be tapped into a reverse wire. I am not exactly sure where to find one close to the glove compartment. I do not want to run a wire all the way to the back-up light unless I absolutely have to.

I'm wondering if there is one by the (automatic) shifter.

Any help is appreciated.

My reverse wire is blue and yellow located in the trunk, but feeds through car.
