where the spring clips into place?

Eric the Car Guys says to put them on the bottom side of pad. Maybe it doesn't matter. put them that when going forward the wear indicator is before the pad. so if the caliper is on the front side that's up, if the caliper is on the rear side that's down.

These springs/clips can be difficult to install, but they always should be re-installed. Some aftermarket brake companies are offering a solution that can be used on the caliper. The clips are designed to push the pad away from the rotor. This can keep the brakes cooler, reduce noise and extend the life of the pad.

Permatex Ultra Disc Brake Caliper Lubricant is a green, nonmelting, synthetic lubricant. It is formulated to lubricate under the most adverse brake conditions, assuring that metal to metal contact areas remain lubricated throughout the pad life. For use on caliper pins, hardware, and the back-side of brake pads.

For example, if the caliper bolts to the rear of the rotor, then the wear indicator should be on the bottom inner. If the caliper bolts to the front of the rotor, then the wear indicator should be on the top inner. By front of the rotor, I mean calipers mounted on the front side of the vehicle.
