What wire do I solder

[rinmancustom]

I cut my rear o2 sensor. I'm just trying to solder a new bosh one in what four wires do i connect to the other wires.

... the whites are the power for the heating element, the other two should be resistance. It's fairly simple, right?
Maby I got those backwards,

The bosh sensor has 2 white 1 grey and one black. The oem o2 sensor wires i am going to solder are 1 blue 2 black and 1 white so what wire goes to what

Better be right when you do it because it can blow the sensor ground on the ECU if you get them wrong.

Thanks for no help THERE WAS A ARTICLE WHERE SOMEONE JUST CUT THERE BOSH SENSOR AND SOMEONE KNEW EXACTLY WHERE THE WIRES WENT. IM GOING TO SOLDER ONCE. SO WHERE DO THE WIRES CONNECT IF YOU DONT KNOW THEN DONT LEAVE A COMMENT.

the two white connect to the two black, blue to black, and grey to white

BOSH----------------------OEM
White--------------------> Black
White--------------------> Black
Grey---------------------> White
Black--------------------> Blue
