the same way I hooked up the speed and rmp for the turbo timer. I was a little confused at first when I read most everyone talking about how they had hooked theirs into the o2 sensors, and people were talking about how to deal with 2 O2 sensors and whatnot. At first I thought then what in the heck is my gauge reading out every time I step on the gas if this isn't right? but Phuong told me it was the exact same signal, and that this way works fine too. I believe the apexi avc-r's tap in their as well.
