Hey, I have the same exact year and model as you. I also have the repair manual page, and have the colors of the 02 sensor plugs, their part numbers, and where they connect to. Private message me if you want any of those

I'm going to upload two pictures of the repair manual. The 4 plugs for your 02 sensors start behind the boot you were talking about. In order, their colors are: Green, Brown, and black. The forth one is Behind your coolant resivour right next to a white cable. That one is also. Black.
