O2 sensor wiring help
On the clip from the car, there is a white, a green, and a black wire w/ a white strip, and a black wire w/ a yellow stripe. On the sensor there is a white, a green, and 2 solid black wires. Does it matter which one is hooked up to which? If so how do I tell?
Thanks!

Engine connector:
Pin1 Wht = O2 signal
Pin2 Grn/Blk = O2 signal GND
Pin3 Blk/Yel = +12v (typically from the Alt SP fuse)
Pin4 Blk/Wht = O2 heater control
O2 connector:
Pin1 Wht
Pin2 Lt Grn
Pin3 Blk
Pin4 Blk
So yes, it does matter which wires you connect to each other.
