Help to install rear view camera

[Bob2016]

2016 Silverado 2500 HD. IO5  I installed a hmi 2.5 to my truck. It added CarPlay. Very happy with the hmi.

when going into reverse the screen goes blue/black says service rear view camera.

I can also go to setting and have option to add grids.

so I assume I could add a rear view backup camera to the existing female plug u def behind the bumper 8 pin.

can someone tell me what and where to get a male harness to plug into the female connector under/ behind the 

bumper. I’ll assume my hmi is ready and programmed for a rear view backup camera.

I ordered a harness from bob’s mirrors but it a female pigtail. So I need a male pigtail. Which I can order from them.

 

I assume.

Resolved. Thanks to this forum. Hmi 2.5 gray connector to

X63a connectors at rear bumper. Use connector x900 tailgate harness to chassis harness x63a.

pins 26 and 27 for video.
