so, widebands...
is there any reason NOT to cut the wires halfway, feed the pigtail through the floorpan, reconnect the wires, and run it? essentially, I want to put my controller inside the car, and don't want to put a big freaking hole in the sheetmetal to pass the connector through. I am planning on using a spartan2 and LSU4.9

As long as you make good connections when you put it back together, I see no reason not to.
In reply to Dusterbd13:
Yes, there's a reason... take the connector apart. The pins should come out of the connector just fine. Then you can feed that through the hole and put on a grommet.
ok, so two different answers, mirroring whats in my head. what happens when you chop it, other than voiding the warrenty?

So you have a choice of getting new pins to go directly to the connector-so crimping them on the cut lines, or splice in butt splices- if you cut it.
Or just putting the pins back into the original connector.
One seems a lot easier than the other. 
just a degree of work.
(oh, and don't solder. the sensor won't work- it uses the wires to bring in and out reference air- I kid you not)
Bear in mind, my primary answer is the more lazy choice.

I thought only the LSU 4.2 sensors used reference air? Wasn't getting rid of that the big improvement with the LSU 4.9 stuff?
AFAIK the only thing special about O2 sensor wires is the reference air problem, which means that you should have continuous insulation to an area with clean air, and you shouldn't solder on the wire, only twist & tape.
pull the pins in the connector, you can use a jewlers like screwdriver or a bobby pin to unlatch the pin from the connector
Take the wires out of the connector. Better plan than a random splice somewhere.
ko. now to figure out how the connector comes apart....
With Molex connectors we used to buy a pin tool to take those apart.
