Solved NO SIGNAL feedback on ATOTO S8 MS Connected to ATOTO AC-HD03LR

I was having problems with getting video feed from my AC-HD03LR reverse camera connected to my ATOTO S8 MS head unit. I checked the wiring connection on the reversing camera and also ran diagnostics on the RCA camera wire threaded to the head unit from the back of the vehicle. What I eventually found was the + power pink cable was not thoroughly spliced and connected to the accessories ignition wire near the head unit. Once I got that connected, the video feedback of NO SIGNAL disappeared and live feedback from the rear camera was displayed. I did seek tech assistance from ATOTO. They were definitely available to give some feedback and check points I needed to verify. I did run their diagnostic plan of connecting the camera RCA to the Front Camera and Video IN while using the AUX feature. Once I noticed the power splice was not properly spliced and connected, I corrected and the rear video feedback appeared. I ran the calibration and the static video painting images of the surrounding from the rear bumper to the front of the car worked like a charm. This video is my result of the properly working feature from ATOTO.
