I didn't use a line converter. Just spliced the RCA and tied into the factory wiring.
Here are a couple options of where to tap in. This is for a 2009 with Navigation, Bose, and Around View Monitor. Not sure if it is the same for other years and option packages...But this is what the repair manual specified.
This is if you tap into the harness going to the subwoofer. The signal is low voltage as the subwoofer has its own aplifier built into it. I initially wired it this way but this signal comes from the Bose amplifier and not from the head unit.
Pin 4, Gray, Amp turn-on signal.
Pin 2, Green, Sub Signal +.
Pin 1, Red, Sub signal -.
This is if you tap in at the Bose Amp. The Bose amp is located under the floor board in the very left/rear of the car. This signal is direct from the head unit. I wired it this way as it seems to have a slightly more full range.
All the wires below are in the 23 pin harness.
Pin 31, White, Amp turn-on signal.
Pin 18, Pink, Front LH +.
Pin 32, Blue, Front LH -.
Pin 19, Red, Front RH +.
Pin 20, Green, Front RH -.
