Hello Guys,
I stalled my Kenwood DNX 9990HD double din over the weekend-Ipod is working, aux is working,gps is working, and mic is working.

For my final step in the installation process, I attempted to wire in the very long purple wire to the reverse wire.

This (through my research) is a red wire with a yellow stripe, located in the wiring harness below the drivers door sill.

Next, I go into my settings -> Camera -> turn on 'R-Cam Interrupt"

And then nothing happens.

I am assuming that where I am tapping into is not the correct wire. Does anyone know which relay/fuse in the dash controls this? Or if not that- what wire?

I was able to get the power and ground and the camera preview working. But that is where I am stuck. any insight would be appreciated!

Thanks guys
