but to really answer your question, yes but the problem is which wires? your model, i believe has 8 pins while later e46s have close to double that amount. you'd have to figure out which wires do what and which pins they go to. a lot more work than to just find the ones that fit yours lol
The ballast unit i have in front of me has one connector for the top of it, that has two pins in it.
This then has two wires that go off to the ignitor, then two wires from the ignitor to the bulb.

I was thinking of just chopping the connector from the car to the ballast.
then swapping that.

The way i see the wiring to the headlamp is:
Car --> Ballast --> Ignitor --> Xenon Bulb
--> Indicator
--> Auto level
--> Halogen (full beam bulb)
--> Backup Bulb

Not sure if that makes sense..
