I really dont know what its called, but it got caught when i was removing the exhaust of and i need to plug it back in, but there are two black wires and i want to see if there is a diagram that i can trace to make sure i connect it back together. It is the sensor passing the downpipe, under the car.
im guessing the rear 02?

After trying to follow the diagrahm, i just couldnt get it. So i got these two ends that i need to put together.
One end is from the rear o2 that is bare, the other is where it hooks. I just need to know which color goes to which to finish the harness for the plug. Anyone got ideas?
