The wiring should actually only be an issue of moving one wire from the high beam plug into the low beam plug on the P5 harness. The P5 has an H4 plug for the low beam, with an adapter that lets it plug onto an H7. Add the wire from the high beam plug to activate the high beam filament and you're golden. You won't have the little corner light on the outside edge of the light though, but you don't need it because the Protege5 has a side lamp.
