how can i convert my 2 o2 scencors to only using one o2 sencor but sill send 2 signals to the ecu
my jdm requires 2 o2 scencors but no one makes headers for 2 02 scencors. 
could i use a single 4 wire o2 scencor in place of the 2 o2 scencors like just run 2 wires to the ecu and either ground the other 2 orjust leave them alone? i need an after market header so i can reinstal my center crossmember. 
i want to eliminate haveing to use 2 o2 scencors would splicing the wires that run to the ecu together and just running them to 1 o2 scencer work?

Re: can a 4wire o2 replace 2 2wire o2s (bmcc72)
to use a 4 wire o2 sensor on a b16a1....
splice the two 1 wire o2 sensors together...
black: splice with the green wire.....
black: goes to a switched power source..
white: goes to the factory 02 plugs....
green: splice with one of the black wires...
i got this from a website i can't find it right now if i do i'll post it up...
my friend got a 4 wire o2 sensor for a integra from kragen and the wire colors were different it was black green and 2 whites.. i'm still waiting on some info so i can do the switch the o2 sensor for him...
