I have a set of American racing headers for my 99 tj. It has 3 02 sensor locations. 2 before the collector and 1 down below past the collector. I'm pretty certain my jeep only had 2 02 sensors. I'd like to use the third spare for my AFR gauge but it seems that it should be located after the collector. Can anyone that has experience with these headers help me out? I'd like to finish this up today or I'd just call ARH. thanks
