The harness won't work. You need a harness from TRS. The high beams on a bixenon projector are achieved by moving the cutoff shield. Inside the projector you have a cutoff shield with a plugner attached to it. The TRS harness has one side that powers the bulbs. When you flip the high beams on with the switch on the column, you supply power to those plungers which pull the cutoff shield down, raising the beam(high beam). The TRS harness is needed because in a regular 9007 application like ours, when you turn the high beams on, the low beams turn off. So if you were to try to wire them yourself, when you turn the high beams on, the cutoff would flip and the bulbs would turn off. TRS's harness has a relay that takes care of that issue and keeps power going to the bulbs and the plungers both to have a high beam
So...yes your DDM bulb and ballasts will work perfectly fine, although they might not be as bright/effecient as TRS's, but that's a different matter.
No, your DDM harness will not work for a bixenon function, only a low beam.
