You need some old ECU plugs from a junked 4G (just so you can use the pins). You also need an injector resistor box from a 1G Teg or a 4G Si and some wire looming. I'm not sure if the 5G IM will work, since all the MPFI conversions I've done have been for ZC swaps, so you might want to look into that... the heads are definitely different.
