RS-485 Dissolved Oxygen Sensor - Figuring out signal pinout cabling

The wiring referred to in the product documentation refers to cable colors, but I can’t cut the cable as I need to keep it waterproof, does anyone know what signal (GND, VCC, 485A+, 485B-) matches which pin on the sensor (1, 2, 3, 4)? I also don’t want to risk of damaging the sensor by guessing and testing pin configurations one by one.
