o2 sensor wiring confusion

CSo here's my dilemma. So from what I've read the 62 ecu for the sr20 s13, the o2 ground goes to chassis. On the e5 Ecu the 02 ground goes to the ecu. I'm not sure if this is correct but I have a s13 harness and I'm running an e5 ecu. Also from what I've read the e5 uses fat 02 and 62 uses skinny 02. Will a skinny 02 work on the e5 ecu and does the o2 ground matter ? I have a Megan dump pipe witch holds the skinny o2. Any of you with a s13 and e5 ecu have any o2 problems? Any help will be great

Anyone? What o2 you guys using with the e5 ecu?

So after searching for hours on end it is true. The e5 ecu o2 ground does go to the ecu vs 62 ecu o2 whitch grounds to the engine. Which pin on the e5 ecu is o2 ground? I know I'm not the only one With this problem. If someone can help me find this it will help a lot of people.

Seriously? Noone?
