I'm not sure what you're doing but it sounds good. THere's a low beam wire and a high beam wire to each aero headlight. Instead of having them go to one bulb per side, you'd split it off so the low wiring goes to the low beam and the high goes to the high beam (per side). It would, in essence, be like having jumper wires from the old harness (unless someone makes a prefabbed harness). Just make sure that the wire gauge and connections are stout.
Good luck.
