02 sensor relocating

[GFORCE99]

All right to get this engine light off I know I have to relocate one of the sensors. you guys know how the layout goes for the 99 es I4 without the headers installes ( 1st the factory headers, then the 1st o2 sensor then the 1st cat., the flex pipe then the 2nd o2 sensor.) right?
Now with the kamakize headers in it like( 1st the k headers, the 1st o2 sensor on the kamak.. pipe, then the flex pipe thingy then the 2nd o2 sensor) right?
Now where do I relocate the o2 sensor witch one, try to have clear directions because I am going to give this to my car shop guy so he can do it, and what do i do with the extra holw if there is one just patch it up?

Thanks to all of you that answer the questions,I get more info from here then the dealer lol.

i believe the first o2 sensor, the one that was in the old exhaust manifold goes after the car...

You need to put the second o2 sensor behind the main cat....Since you put on headers, you took off the precat therefore your 1st and 2nd o2 sensor doesn't have any cats in between....Just tell your mechanic to put a bung after the main cat and plug up the oringinal hole......

you can get the bung and plug at summit racing.........I believe its www.summitracing.com. In the search, just type o2 sensor bung and it should come up.....
