backup camera pigtail color coding and pin# selection

[Hosta]

On my 2015 silverado crew cab, my tailgate fell off, shearing the backup camera connections, leaving only the 6 pin plugged into the main harness, under the bed. Purchased an aftermarket pig tail, with colored wires: white, blue, yellow (1st row) gray, red, and black (bottom row) as viewed from the back. The vehicle side wires are colored yellow, red, brown, black, black, and white. On the truck side, the 6 pin end connector is numbered, and there was a short piece of black wire still inserted at the corner, and all the other wires were yanked out of the connector. My question. Which colored wire from the vehicle side spices to the aftermarket pig tail?
