haha I posted there too. 
I searched but there seems to be contradicting answers. Some one said that it's the bottom 2nd from the left (looking at back of connector), but of which connector?
He said that it's the 18 plug one, but I don't see any!
The one in the middle looks kinda blue, yet I heard the wire is grey.

IMO, I would wire It In as close to the ECU as possible. That way It may or may not Interfer with the Immense heat our motors produce thus potentially offsetting the A/F readings.
I'm a boost creep...

Don't go to the O2 sensor; there's too much chance of disturbing the shield wire and grounding the signal. Then neither the ECU or the gauge get a signal.
There's an ECU wiring schematic in the EFI chapter of the 89 FSM (download it from www.fc3s.com) that shows which pin is the O2 signal.

Ok well i dont remember what pin it is but if you look at the middle section you will see a solid grey wire. It looks like it is black but apparently its "Grey". Anyways, its fairly thick, but you should be able to see it. It took me a few minutes to find it but thats because i was looking for a grey wire when indeed IT LOOKS BLACK
