Hi all! I am installing one of those Tesla-style Android head units in my 2007 RX 350. So far so good. I got everything working (including the OE backup camera). I was replacing an old GEN5 Multi-function Display head unit (Toyota 86110-48320). I did need to MacGyver a few things with my wiring harness (moving pins) and in so doing, forgot where two pins were supposed to go. I kind of know, but am not 100% sure. It's two wires coming from the head unit; each carries 2.5v... which could be for LEDs or lighting. Might be important... might not. Nothing changes with the voltage when I'm in ACC or have the car completely powered. They stay constant at 2.5v (unless I turn off the car completely). My question: Does anyone know what these two pins (#9 and #10) are for on the old GEN5 unit? THANKS!

I've searched the forums, but could not find what I was looking for. Apologies if this has been asked (and answered before). I am installing one of those Tesla Style head units in my '07 RX 350 (with ML audio and nav). Got almost everything working... except for the OE Camera. I know it's a 6v device, so I bought a step-down converter. I'm good from the radio side. I have a harness that came with the radio, but I think the pins are incorrect. From the radio I have a switched 12v that comes on when I put the car into reverse. I've got the step-down converter hooked up, but don't know which pin in the harness takes power to the rear camera. I have a signal wire carrying 2.5v (from the radio) that goes into a second harness which should go back to the camera. I the typical RCA connector, in that harness, too. This can't be that hard. I need power, ground and a signal. Can anyone help?
