Just wondering were I can find wiring diagrams? Trying to wire in a back up camera and mirror turn signal.

 

Neither of those items are on any diagrams. What good would diagrams do?

 

Run the mirror signal wires to the front turn signal and splice into the harness, use your test probe light to confirm signal wire, if I remember yellow is the left side, green is the right, black are ground.
As for the back up camera follow the instructions in the kit, most are powered by the back up lights
