I have a 2021 Sierra SLE X31 with UVB HD rearview camera only. I removed the rear seat and i have no harness for video module. As I see it I need to do the following -
Run three wires for the K157 module.
Wire Numbers -
1102 GMLAN serial data #2 GY/GN to pin 9
1640 12 volt positive RD/VT to pins 1 & 10
2751 ground BK/WH to pins 3 & 12
Also add camera cables to side mirrors and front. (I added cameras on each mirror and front grill but not satisfied with results on an external 7 inch monitor)
I also added the Brandmotion Fullvue Camera Mirror - FVMR 1100.
I have located 2 mirrors, the third brake light with camera and the K157 module. Will this work or am I missing something?
I just purchased 2022 Yukon SLT with HD surround system and really need to add the surround system to my X31.
Any advice would be appreciated.
Thanks
