You are going to need to get someone to weld an O2 bung in your exhaust after the cat or get a cat that has the bung in it. For the O2 wiring you will just need an extension harness (check my signature below if you need one) to connect the harness you described to the new O2 sensor . The best place to get a secondary O2 is Amazon, the Denso brand. Here is a link to the one you will want:

i have heard of you befor! you come highly recomended from alot of boards! heard alot of good things about you and your harness's the exhasut is after market and DOES have a bung all ready! i do have a 02 sensor that came with the car previous owner included it, it does look a little diffrent onthe tip that goes in the bung but it is a 4 wire will it work? once i figure that out im ordering your harness, and also how do i wire it to my car since theres no existing wiring? THANKS FOR THE REPLY!

Are you sure there is not wiring? was it cut off and you do not see it? tucked into a harness somewhere? My point is a factory EK has to have it unless, your harness is different?
