For my powered device, do I just run the other wire (the black one) to the chassis since there isn't a return/ground wire?

Yes... What I did was peel the carpet back a bit and there was a bolt that I loosened wrapped the ground to it and tightened the bolt.... All worked out well!

Hi Lisa, connect the BLACK wire (ground) directly to the battery and the RED wire (power) needs a 15 watt inline fuse. Best of luck.

I have this box as well . you will run your wiring to the back side of the connector.

Yes you ground your device anywhere you find a good ground and then run your red(positive) wire to the fuse box using the Add-A-Circuit.

Connect the Red Wire to your the wire going to one of your Backup Lights and the Black Wire to the chassis making sure that you have a good ground. The idea is for the camera to turn on when I put the vehicle transmission in reverse.

Cut the plug off the end and connect it. I don't know what color wires that are used so skin back the insulation to see which wire goes to the ground, hot lead and neutral.

You must cut the end off the cable on the power supply and strip the wires back and use those wires to connect to your controller. Make sure to get the polarity correct.

You should be able to either ground that connection or use a relay unit. There are several videos on YouTube that explain how this is done.

I think yo have to connect the extra wire. Red one according to the pic. But not sure if it has to be live or ground

You would still need to ground it separately. Usually you can find a suitable ground very close to the fuse box.

U will be fine. I had two wires and connected them accordingly. I left the middle screw unattached. Mine is connected to security system box. All works just fine.

My installation is grounded to the negative side of the battery, I recall the manufactures installation instructions showed a negative and a positive ground diagram so you should be able to do either.

There should be a negative and positive terminal where you can put a wire in and clamp it as seen in the picture near the bottom corner the two terminals. You'll need to take a 9V battery and get one of those connectors where it connects to both of the battery's leads and turns them into a red and black wire.Put those wires into the terminals respectively and it should be powered

The black wire should be the ground wire. I believe it should of had a round "ring" end, I'm guessing it got left off at the factory by accident.

Just wire one end to your power supply, being careful to get the polarity correct. You should protect the exposed wires on the other end.. I just covered each lead with a small piece of heat shrink tubing.

Just connect the 2 wires, hot and neutral, to the GFCI. Ground isn't needed.

Older installations won't have a matching ground wire. The ground wire is for safety, but not strictly necessary. Simply cap it off as you do the other leads and be very careful none of the wrong wires touch each other when you push the box in.
