I looked at additional wiring diagrams for the CRV. I made several errors in my assumption when I used only the colors of the wires for the diagram. The wire colors alone can't be used to match up the wires because some change their color once they get up to the dashboard. With the additional details I can also now see that the pinouts between the CRV and Civic cameras are different.
I can't be certain that the colors between camera models is a correct match for their indicated purposes. Although all but the brown wire is present in the CRV's camera diagram. Looking at the CRV and Civic camera connectors the brown wire might take the place of the green wire for the mode select. My thoughts come from a similarity between camera connectors. In the CRV camera connector the blue and green mode select wires are next to each other. In the Civic the Blue and Brown wires are next to each other.
There is one other wiring detail that will need to be completed for the reverse camera mod. Pin 14 on the i-mid connector will need to be wired to the reverse lighting circuit. On the Civic this circuit is a brown wire coming off of fuse B21 in the fuse box under the dashboard.
With all that said, here is the CRV's corrected diagram with changes in bold. I have also rearranged this information to pertain CRV camera and added additional details.
