My question is about the back up camera. Everything was working well in the garage, even with engine running. Once we got all the trunk trim pieces in and everything buttoned up, we got static on the display trying to back car out. Weird. Why? Anyway, I ordered the filter you suggested. Can you please show, or explain, how this gets wired in? It's the last piece of a long puzzle. Thank you. Thank you. Thank you.
Sure, I drew in the PAC CSS12 noise filter and additional ground wire on the photo.

You have to disconnect the backup cam red wire from the relay and insert the PAC CSS12 in between them.

It has 3 wires:
The red input wire connects to the 87 yellow wire from the relay
The blue filtered output wire connects to the red backup cam wire
The black wire connects to the grounding point

I also used a wire to connect the grounding bolt next to the lights to the main grounding point below that the battery negative is also connected to.
