1994 945T o2 sensor wiring

Post by ZachW »

I just got a 1994 945 turbo wagon, the car came with a 3 gauge pod for :
Boost, Voltage, Air/Fuel.

So my question is:
Which wire do I hook the + lead to from the A/F gauge?
The sensor is about an inch and a half back from the turbo.
I have the - grounding to the block already.

I've done some searching on this forum and Google and cant seem to find the answer.

This is the wire setup:

Black is labeled 4
connection 3 is blank
First white is 2
second white is 1

And then that connects to the clip you see next to it. That goes as follows.

Green connects to 4 (black)
Empty 3
Black connects to 2 (first white)
White connects to 1 (second white)

Thanks for any help guys, I use this forum alot! Figured its time to make an account now that i'm on my 5th Volvo.
