How to replace the rear brake pad sensor?

Hi all.
I got the brake pad warning light on and had to replaced the pads. However, the pad sensor is a one-use part and I found out that it needs also to be replaced by a new one, in mi case the rear sensor. I have bought an aftermarket replacement and I'm ready to install it, but the dealer removed the broken sensor when they changed the brake pads so I cannot see now where is the sensor located and if the brake caliper has to be removed or not to do the installation. It would be nice if someone can provide me with some guidelines and the torque values for the screws of the brake caliper and the wheel.
Thanks!

Yes, you need to remove the brake caliper to install the new pad wear sensor.
One sensor for the rear, on the RHS only.
The sensor is clipped into a spring on the inner brake pad.
You need to remove this brake pad from the car to access the spring.
Then open up the hole in the middle of the spring by squeezing the two ends together, insert the little round end of the pad wear sensor into the hole, then let go of the spring and allow it to grip the sensor.
Edit - wrong!
Instead, pull the spring out of the pad, insert the end of the sensor into the hole in the middle of the spring, then push the spring back onto the pad. Make sure you do it "correct side up", see pics below.
Then, with the sensor attached to the pad, feed the sensor cable (electrical plug end first) back through the gap in the brake caliper, reinstall the brake pads, reinstall the caliper, do the caliper bolts up, reinstall the anti-rattle clip, and lastly plug the brake wear sensor cable back in to it's slot up in the wheel well (you may need to hunt around with a torch to find it!).
Pics of the pad & sensor to follow.
