Good news, I followed your advice and found the wire in the front harness - no surprised it's the same color, black and red. So I'm going to ask the shop to connect the power source to turn on with the ignition, and the magenta wire goes to that black and red reverse wire. That should work, right? Huge thanks for taking the time to help...

Thanks, Joe. I previously used a Magellan with a wireless backup cam, and there was a black/red wire in the tail gate that served that function. It actually worked, too. The Magellan GPS was awful so I replaced it with this Pioneer. I guess they could run a wire from that red/black wire in the tailgate to the Magenta wire in the Pioneer harness, correct? Or, perhaps better, find a similar wire on the harness up front.

Thanks to 493008 for sharing those videos above, very useful!

Just had a 4100 installed on my Sienna on Monday, plus Metra - License Plate Back-Up Camera. I think the tech at Best Buy (don't laugh, they matched Amazon's price of $550 and I had gift cards) wired it incorrectly. He did not connect the reverse sensor wire (magenta color, it's labeled). So the camera turns on, but doesn't turn off. I have to hit the X at the top right corner to go back to radio mode. He told me this is how it works, after some searching now I know better. Even worse, once I connect my iPhone and go to CarPlay, it doesn't show the camera no matter what. Even w
