Factory back up camera to aftermarket HU. Talk through 09 Yukon/Tahoe 

Thank you so much for this. You are a cold dude to figure this one out.

Thank You

Where to run rca after I slice?

Is that blue wire that comes from that gray connector the wire that also enables the parking assistance grid lines? I have my factory backup cam successfully mirroring the image from the rearview mirror to my aftermarket head unit...however, I don't have the parking assistance guidelines.

Is that a factory backup camera with aftermarket radio

What wires from the rca plug I need to splice into? Is it the blue(-) and white ( +) wires?

I want that mirror screen for my 2002 truck lol

Well done man
