LS2 oxygen sensor What is the difference in the C6 rear o2 sensor than the previous ones? Are the wires in the same locations for power and what not? I know the connectors are different, but I was not sure if the wiring was crossed up as well.
There is more than one connector style, but should be:
'odd' shaped connector that looks like a 5 position but is 4:
A. tan - low sig
B. purple - high sig
C. pink - ign +V
D. light green - heater control
If you hold the connector so the clip is up and look in at the terminals:
D is top left
B is below D
C is top right
A is below C
Rectangular connector:
A. tan - low sig
B. purple - high sig
c. og/white heater control
D. pink - ign +v
If you hold the connector so that the clip/lock is UP and look in at the terminals:
A is upper left
B is just below A
C is upper right
D is below C

Thanks for the info.
Yea the front Corvette has the wide connector, and the rears are the typical squared ones like on the Fbodies.
Did the LS2 rears change from the LS1 rears as far as you know? I am reluctant to power them up as is because the connector did not fit direction into my car, the notch was different. I was wondering if the wires may need to switch, or if it will work at all.
It was a free set of o2s and I was going to play around with going back CL in my car. I trashed my last set of sensors because they were bad, never got new ones and don't really want to fork out the money lol

Bank 2 sensors on the F-bods are like this:
Rectangular connector
A. tan - low sig
B. purple - high sig
c. black - grnd
D. pink - ign +v
If you hold the connector so that the clip/lock is UP:
A is upper left
B is just below A
C is upper right
D is below C
you could use a terminal removal tool or something similar and pull the connectors and swap them; the terminals are the same type but with the heaters being possibly controlled differently, I'm not sure that they will work.

Ah, got ya. Prob won't work because they were free lol
Looks like they plug up the same though. I will just give it a shot and if it doesn't work I will just buy some. Thanks for the info.
