O2 sensor wiring....
I'm replacing the sensor and have to splice it in because the MFG connector is shot (heavily corroded, came apart when removing old sensor)....
On the Bosch O2 sensor I have;
Grey
Black
White
White
On the truck I have
Orange
Red
Grey
Black
Is:
grey-orange
black-red
white-grey
white-black
The correct order?
I am assuming that since the orange & red wires are thinner than the grey & black ones on the original harness, they are the computer inputs, and the grey/black are the heating element...
Am I right?

Just saw this post.
I replaced mine o2 over the weekend - stupid easy to replace, still can't believe how easy it came out - got it with an o2 socket and regular socket wrench (little PB blaster first). I was dreading this for a year. Anyway you figured out the correct pattern .
