Is your bixenon low beams or high beams that you're having trouble with? And how about the turn signals? I'm a bit confused as to what you're trying to fix. Again, pics or a better description would help.
If it's the high beams, you should have a separate hi beam plug that you can splice into the solenoid wires (or buy an adapter) that goes to the cutoff shield. I'm assuming you went with an H1 mini bixenon projector. I just retrofitted a set of P5 headlight this past weekend and have my stock P5 high beam plug going to a 9006 male to Molex female adapter...which plugs into the solenoid connector.
