Default 02 sensor plug

I have a 2000ex and got dc headers for it, the new 02 sensor plug is in the middle of the header, my question is where do i plug the other end into?

on 2000 EX the primary goes in the downpipe of the header right before the cat and the secondary goes into the cat. There should be a place to thread the o2 sensor in right on the top of the header by the engine and a second spot on the down pipe. You need to plug the top bung and put the o2 sensor on the lower spot.

i know this is an ebay header, but its a good diagram

^ it has lines pointing to the 2 o2 sensor bungs, with the header you should have a gotten a plug for each hole like that picture shows. Plug the top hole and put the primary sensor in the secondary hole farther down the header, then i think you just leave the secondary sensor alone since you've got an EX.

there should be a harness that you plug it into just to the left of the header, the one you unplugged the sensor from.
