Oxygen sensor wiring.
So I took my truck in for the cruise control recall and had that done.
On the way back home the check engine light pops on and the scangauge informs me that my rear 02's heater sensor is dead.
A couple months ago my front left 02 died after lasting 150k miles. I decided to replace both front 02's at the same time and left the rear one in because I figured it didn't control a/f ratio so i'd wait until it died. Well now its dead!
I kept the front 02 that was still good and wanted to splice it in to the harness for the rear.
To make a long story short I messed up bad. I didn't make note of the wires position before I chopped the dead 02 off the harness. Afterwards I noticed there are two white wires. Now I need help figuring out which wire goes where.
Bonus picture: My grill got trashed when a big crow smashed straight into it at 70 mph 6 months ago. This xmas my wife got a new grill for "chippy". It's aluminum and pretty flimsy but I like it.

I greatly appreciate it! 
I was about to go out in the rain and get under my truck to look at one of the other 02 sensors, the main problem being the wires are all twisted up and underneath that heat protection fabric/plastic so i'd have to cut it off

I got some bad news for you, you can't use one of the front sensors in the rear they're a different type of sensor. The front sensor is designed to switch back and forth rapidly at the stoic mixture ratio while the rear type slowly wanders between a min and max voltage, so the computer is going to complain about the response it gets from the sensor you're trying to use and you'll still have a check engine light.
