How to properly setup the O2 sensors w/o stupid stuff
ok after reading about 1234234 different threads with people having sooooo many issues with o2 sensors and check engine lights imma post how i had my car setup when i had a header
the video you will see later will be with my turboed vehicle but you will get the gist of it
you DONT have to cut wiring
you DONT have to buy spark plug foul crap
if you cant easily get the 1st o2 sensor to line up BUY 2 REAR O2 SENSORS they are exactly the same albeit longer wiring, i was able to use the factory ones with no issues
alright down to business
for the front o2 sensor
for the rear o2 sensor
carsound makes a catalytic converter WITH THE O2 BUNGS ALREADY INSTALLED, if you get the one with 2 bungs, plug the first one, you want your exhaust to go:
1. midpipe o2 sensor near where all 4 collectors meet
2. catalytic converter
3. rear o2 sensor
as for the wiring:
the harness itself has A TON of slack to it, unbolt it from the firewall and remove the o2 sensor wiring from the harness, re sheath it in a new loom and move it where you need it
heres a video that sorta explains it, and yes i cut my loom off to show you guys how to do this, you guys owe me some zipties

On my GK, the sensors had different plug sockets front and rear, 1 was male, 1 was female.
Nive to know now, O2 sensor CEL was ne of many problems I had with the GK. luckily the RD's seem to be less sensitive.

I did this exactly. Carsound makes a cat with one O2 bung already in it in the back. I made sure it was the right cat for my car too. Didn't work.
We'll see. I'm sitting here waiting for the CEL to come on with the stock parts. My Tiburon is a Rev A. Maybe that has something to do with this whole thing.
