Maybe a wiring error. You have to make sure you tapped into the correct wires and that the new wiring is correctly done.
Rear window defroster coming on? - Sounds like a new variation on the starter motor suddenly coming on without warning.
The relay coil should be energized by the headlight circuit. It should be fed from the low beam light wire and the other coil terminal should connect to the common wire of the light plug.
The relay contacts (NO) should be wired in series between the positive terminal of the battery and the positive feed wires to the ballast units.
The negative wires of the ballast units should be grounded to the same point as the main negative cable of the battery.
If you have any doubts or questions, you should consult with a local automotive electrical / electronics shop.
