You have two challenges with this.  The bulb to the light housing and the
connector to the bulb.  The wiring issue is the easiest you either cut and
splice the correct connector in place or make an adapter which would be more
difficult but not impossible.  The bigger problem is that 9004 and H4 bulbs
use two different methods to secure to the light housing.  If your goal is
better light output from stock US market rectangular headlights circa 1986 -
91 changing the bulb will not do much.  The problem is the lens and
reflector not the bulb.  There are cars that use a four bulb system and both
the high and low beam bulbs are the same style, it is the reflector that
differentiates the two.

What problem are you trying to cure and on what year van?
