Hi, new to the forum and have a question about a 400E oxygen sensor. I bought the bosch 13275 universal oxygen sensor and need to know how to splice the wiring. The new sensor has a black, gray, and 2 white wires. Black is the signal, gray the ground and the 2 whites the heater. Original sensor has black, brown, yellow and black with blue stripes wires. Does anyone know how these match up to the universal sensor?
