Front Brake Pads

Hi,

I'm new here. I went to change my front pads on my 2000 Passat 1.8 T, non AWD, and discpvered I didn't really need to change them, but discovered the pads in it have a couple of wires plugged into one pad. Is this stock? the new aftermarket pads don't have a place to plug a wire into. Any help? Are these necessary wires? Any one else using aftermarket pads?

Thanks for the help,
Perry
