And it's finished! I ended up going with the PAC controller. As near plug and play as they come. Hardest part was running the video cable. Made sure to place it as center as possible to avoid any possible issue with the side curtain air bags. Also, removing the A-pillar was a bit tricky. It doesn't just pull out. You need to slide it UP after you pull it out a bit. There's a slip on post/tab near the top holding it in place. Getting it back in was a chore as well.
The PAC controller provides reverse, parking brake, and VSS if needed by your headunit. Means you don't have to tap reverse signal from the camera power (brake light), or run a wire down to your parking brake ground. There are 2 Illumination wires. One directly from the car harness and one coming out of the controller. Some cars don't have Illumination from the harness. In my case it did, but either wire will work. Only issue with the controller was programming additional steering wheel functions. The instructions are not clear / incomplete. Each time you program you have to go through every button function 1 through 13, not just the function you want. Also, for each function not supported or that you want to skip, you must tap the programming button on the side of the controller to skip it.
For my Pioneer headunit, Preset+- actually did tuning +-. I skipping Preset+- and used Track+- instead to get the desired preset changing result. I also swapped + and - since the Pioneer layout displays presets from top to bottom with 1 at the top and 6 at the bottom. The End Call button default on the steering wheel brings up the Phone Menu for Pioneer. I left this alone and added End Call as a long press on the same button. I set Mode to change sources and used the Voice Activation button to change bands (FM 1-2-3, Sirius 1-2-3, etc.), with a long press to activate Google/Siri VR. The Info button is used only to change info on the right side of the top display (mileage, etc).
Anyway, here it is!
