Factory equalizer upgrade

Picked up a factory Ford equalizer...the wiring seems straightforward to me. I understand that the wiring harness was different with a factory-equipped car...but if I spliced into the power/ground/backlighting from the radio, then spliced into the signal output wires (between the radio and the amplifier), in theory it should work, no? It would just be modifying the sound signals on their way to the amp/speakers?
