Answers: I don't capture it, did you have them installed and are near 2 wires dangling? Well typically there should be at smallest 3 wires. Power/Ground/Accessories. Theres probably another one with the AV Input too.
For
Power - touch into another 12 volt source in your vehicle,
Ground - a screw mounted onto the chassis of your vehicle(one thats not colored)
Accessories - Theres many different places to slap into but I typically just slap it into the fuse box into the radio fuse.
