What year/model is the truck, and which navigation did you install?

I have a 2012 chevy tahoe lt texas edition i installed the gm hard drive i had a harness made and everything works...i just need to know what cables i tap in too and which connections i hook it up too

You will need to connect the 2 wires currently going to the rear view mirror to the back of the navigation.

 

You will need to cut the wires and isolate them from the mirror as you will no longer be using the display in the mirror, and the driver is not powerful enough to reliably feed video to both displays.

 

The wires should be as follows:

 

At the rearview mirror:

Camera Signal+, Pin 6, White Wire

Camera Signal-, Pin 7, Dark Blue Wire

 

At the back of the navigation

Connector X4

Camera Signal+, Pin 5

Camera Signal-, Pin 15

You will need to cut the wires and isolate them from the mirror as you will no longer be using the display in the mirror, and the video driver is not powerful enough to reliably feed video to both displays.

I considered doing the same thing the OP is wanting to do until I found this out. Instead, I ran a second camera to the 3rd brake light on my Sierra Denali, and had that run to my Kenwood DNX890HD nav unit. Now, I use the OEM camera at the tailgate for hooking a trailer or seeing what is directly under my rear bumper. And I use the top 3rd brake light camera as a wide angle field of view behind the truck. It works quite nicely.
