Problem with my O2 sensor??!!??

This has been troubling me for some time now. I have a 96 honda civic
non-vtech and i have my catalytic converter on my headers. Which makes me
have two o2 sensors. Well i got new 4-2-1 headers and there is only 1 o2
sensor hook-up. Well i am running on a check engine light because i only
have one o2 sensor plug up. How can i get rid of this problem??? I dont want
to run check engine light, please help me out.

 

drill & weld nut where the 2nd o2 sensor should go..... or fit an
appropriate resistor to the 2nd o2 sensor wires. unsure on value, or if this
will cause cat damage (ecu detecting lambda=1 because of resistor, where it
might not actually be running at that value).
far prefer the 1st option of drill & weld a nut in place.

Where should i drill the second O2 sensor at to get rid of my check engine
light. Should i drill after my headers go from 4-2 or should i drill from
2-1 or after my pipe already comes to 1??

 

drill where the pipe is single pipe - as it is on the original exhaust.

also, if you still have it, try to drill in a similar location to the stock
lambda position, as this is where the ECU is expecting the lambda feed to be
from (theres difference between the manifold/header and the rear box)

and as a good precaution, dont have the lambda sticking downwards. have it
on either side of the exhaust pipe, or on the top 1/2 - this will stop
stray objects in the road from hitting the lambda sensor
