uhh . . . is that your primary o2 sensor? You can always slap it on the header if it has a place, or yo can get an o2 simulator since I know that the 96-00 civics are obd2 and have 2 o2 sensors. You can also take the header down to a shop, have them drill a hole in the header or the downpipe of the ehader, and weld in a o2 bung for maybe like $30 and slap the o2 sensor in there. Couple options for yah
