Get under the car and look up by the back of the motor follow the exhaust they should be accesable. You cant miss them.

What he said. Just reach up and unplug the wire, unscrew it with a 7/8's box end, screw the new one in, and plug it back in. Done. Shouldn't take more than a couple minutes once you get under the car.

it can be difficult to get to the plug, get a good flashlight

it may also be really tight from rust and the heat of the exhaust. so some penetrating oil maybe be needed
