ignition wiring.
You wire it as if you were wiring a 5 pin ECU. The side of the 4 pin ballast that is connected to the ECU simply does not do anything when hooked to a 4 pin box.
The only advantage to doing this is that if you ever "need" to run a 5 pin ECU, either a 4 or 5 pin box will plug in and run.
