What's the Pinout to go from the camera's 6 wires to the POE Cat RJ45

MY Lorex LNB4321 camera stopped working, it had gotten water in the cable connection and the female RJ45 molded end had corroded away. I called Lorex but they wouldn't tell me the pin out to replace the end. I know the red and black go to the power plug but I need to know the which cat5 wire corresponds with the wires from the camera.

(gray, brown, purple, blue, orange, yellow)

I reverse engineered the plug from another working camera with a continuity tester. The connection for the Lorex LNB4321-C is:

Camera Cat 5-6

Gray<------------> Brown/white

Yellow <---------> Blue

Orange <--------> Green

Brown <---------> Orange

Purple <---------> Orange/white

Blue <------------> Green/white

Red <---> Power Plug

Black <-> Power Plug

Blue/white and Brown are not used

Thank you so much. Your pin-out worked for my LNB8111-C camera. Except I doubled up the BRN+BRN/WHT-> Grey and the BLU+BLU/WHT->Yellow because POE uses pins (4+5) and (7+8). So basically I used the cables you had left over.

Hello Alvaro, can you explain what you mean by "doubling up" on pin 5 and pin 8?
