From what I can gather, people have only tried installing facelift headlights onto older cars and required CAN coding (suggesting the wiring harness is largely compatible?), i havent seen any references of people going the other way round of installing projector headlights on a facelift car.
If I had a facelifted car, I'd probably buy a pair of projector headlight assy's off ebay for peanuts and try this instead, the laser/led projectors are WAYYYY brighter and sharper than the facelift LEDs.. I drove a loaner with it at night once and couldn't wait to return the car.
