Double wrong.

I am speaking of the FRONT O2 sensors. They are both black and interchangable.

And I'm not kidding about the length of the leads. They are about 5-6 FEET long. runs from the ** up and around the back side of the head to the front DS near the oil filter housing.
Having the connectors on the PS of the head would have been much easier for replacement, etc.
As it is now, I couldn't see where i puled the leads out of and they are just back there on something. I know I didn't get them routed as stock. And there is no way to get a picture of what is back there.
