Can anyone walk me through a CRUX CTY-02 Backup camera install?

I have removed the old handle and wires, installed the new handle/camera and connected the connector while using the factory cable runs through the tailgate and into the bottom of the truck bed. I have 25ft of an rca cable to run and a several feet of red and black cable to ground and somehow get into the reverse 12volt power supply of the backup lights. Anyone done this yet? Any pictures---

 

Did you get this to work? I tried, didn’t work.

 

Mine is working fine now but only after I took it to my local audio installer and he did his thing it works like it’s supposed to

 

I was able to install this camera.

So a few tricks and points. I may not have done it the "right" way, but it works.

1. The instructions really suck. While it can be a pretty straightforward install, better instructions would help. There is a decent youtube video about a differnt camera but it does show the places to run the cable so it's good to search it out. https://www.youtube.com/watch?v=hBk7dfWCgR0&t=330s
2. I pulled 12V power from the driver side reverse light. Actually I just used wire taps and pulled both the + and - from there. I had to look up the wiring diagram.
3. I pulled the reverse power for the sradio from the wiring harness in the footwell. In theory, I could have pulled the power from the reverse light also, but whatever, this worked.
4. I ran the cable mostly along the frame and poked it up through a grommet that is under the outside rail of the driver seat. I should probably seal that back up with something.
