Welcome. Sounds like an electrical nightmare. You should know these forums well by the time you have it all back to "normal". Good luck!

the harness that is unplugged is probably a wheel speed sensor, which would cause your ABS and trac lights. those will throw a code that can be read with something like a TechII at your local GM dealer, so that will point you in a better direction. if your low coolant light is on, check around the lower intake for leaks. sometimes just an air bubble around the level sensor in the radiator will throw that light. i believe there's a procedure detailed in your owners manual about bleeding the cooling system. long story short, overfill your overflow bottle, make sure the car is hot enough to open the thermostat, and open the bleed screw on the thermostat housing until you have a steady stream of coolant. there are also two oxygen sensors, so make sure you get whether the code was for bank 1 (pre-cat) or bank 2 (post cat).

They are both bank 1 just sensor 1 precat and sensor2 post cat

what he said. about $60 either way, and you'll need a special socket and PB blaster if you plan on doing it yourself.

I've found that warming the motor up to operating temp before removing the rear o2 helps it come out easier too. I had a buddies get stuck on his truck so we just started it and kept trying to turn it every couple of min until it came out. Worth a shot if it's the rear, I wouldn't try it for the front one though.

Looks nice
