Need some help w/ the rear O2 connectors (Y33)

Sup guys, not exactly sure where to post this cause I can't seem to find a 'technical help' area. There aren't too many forums out there that are active that discuss the Y33 so I thought I would post this up here to give it a shot.

I was wondering if anybody would be able to get under their car and take some pics of the rear O2 connectors for me. I bought my Q45 without knowing that the rear O2 connectors were CUT OFF from the body harness, and the Check Engine light must be gone cause that doesn't even light up. So in an effort to get my car passed emissions/smog so I can register the car and legally drive it, I need some help.

I ordered two rear o2 connectors off of wiringspecialties.com and got under the car to try to wire them up to the harness. Problem is I can't find any information on what each wire is. When I was under there I saw that the car has 1 black, 1 white, 1 yellow/red and 1 green/red wire for the car. I am installing new Bosch OEM replacement o2 sensors in there which has 2 white wires, 1 black and 1 grey wire. As far as I am concerned, the two whites are the heater wires, the black is the signal and the grey is the ground - please correct me if I am wrong, but that is what I have been able to find out online.

If you happen to know what each wire is, that would be great. If not, if I could just get a pic of the connector and where each wire goes in relation to the plug then I should be able to duplicate that and get this thing going. I just failed emissions after trying to wire them up and it looks like I did not do it correctly. It would be a huuuuuge help!

Thanks
