The leads for the sensors are 12-18" long. The plug for the front will be under the frame near the transmission. The rear plug was probably routed around behind everything and coiled up near the T-Max itself. The clips you are talking about are part of the plug assembly. Take a close look at it when you have cut the wire ties and have some slack to play with. It is not real obvious where the plug comes apart. Look for the 2 locking tab holders on the computer side of the plug. Then you will see the tabs inside them. 80% of the plug is on the O2 side, not the computer side. Using a very small screw driver you can release them one at a time and work the plug apart. It's real obvious once it's apart but hard to see when plugged together. Hope this helps.
