1987 911 Carrera 02 sensor


Vehicle Information: Model: 911 Carerra; Year: 1987; Body Type: Targa; Engine (type, size, modifications): 3.2l cat bypass and chip; Total Mileage: 96000;

When replacing 02 sensor is it critical to go with orignal bosch 3-wire (green, yellow, brown) or will universal bosch 3-wire (black, white, white)work as well. And if so is the black wire spliced to green with the two whites going to the yellow and brown?
