Header on b16a but the header only has one O2 sensor

Im trying to complete my swap but have run into this problem. I was told to get the Integra ls header for 94+ Integra. I did but now notice the header only has a one hole for an 02 sensor but there are 2 off the engine. What to do??
Thanks

What engine are you talking about? I would probably say that you should get another o2 bung welded in but there might be a better solution.

putting a b16a1 in my 90 integra.
thx

I just have 1 O2 sensor in my B16A, I just ran the same signal to both points on the ECU.
