replace 2004 bank1sensor1 O2 sensor?

I have a P0135 code on my 2004 2.7L extended cab Tacoma, which reads as malfunction in bank1 sensor1. I can see where the sensor sits ahead of the convertor on the exhaust, but the wire leads up into the floorboard through a rubber gromet. Can someone tell me where it goes and how to best access the end of the cable? Should I take off the passenger seat and somehow get under the carpet? I already have a replacement sensor that has the rubber gromet sitting on the wire between the sensor and plug.
Thanks in advance for any help!

pop the grommet loose and it should come out with the connector, disconnect it and put the new sensor in

Thanks for the suggestions.

I will try popping the grommet in hopes that there is enough slack for the connector to pull through the hole - sounds like a good idea. And thanks for the link to the '96 fix - it seems that the setup on the '04 is different.

I will report back on how it went - maybe with some photos of the cable location...

I popped the grommet and found that there was no slack. I had to get under the carpet beneath the passenger seat to acces the plug - not much fun, but it is done. I had to go to the dealer to get the custom nuts that hold the sensor and its annoying mini heat shield in place - the oginal nuts were toast.

I am attaching a couple of pictures - sorry for the blurry shot of the plug. the first photo shows the grommet from below and the second shows the wire coming up throught the floor and the plug under the carpet.

Before too many others read this thread I have to admit to a mistake - I replaced the bank1 sensor2 sensor that reads an error message of P0141 - not the bank1 sensor1 sensor (P0135) that starts this thread. I had the P0141 message last fall, ordered the sensor, and cleared the error. When my check engine light came on last week, I assumed it was the same sensor even though it read as P0135 - bank1 sensor1.

So, I will be ordering the other O2 sensor tonight and replacing it sometime next week. I'm not sure why I would have different codes from last fall and this spring...well, I will now have two new sensors.
