H7's use exactly the same plug as H4's. You (or a mechanic) need to remove the front bumper then unplug, unbolt and remove the H4's then bolt in the H7's, plug in and refit the bumper. 1-2 hours max. I and many users here have done this so if anyone tells you any different then they don't know what they're talking about.
The only main difference (apart from the improved light throw) is that the dipped beam goes out when the main bean is lit. This can be fixed by using VCDS, OBD11 or Carista to code the change. I live down the M6 jnc23 and will happily code if you're ever passing this way. Takes 5 minutes.
Other than that my advice is to change the bulbs in the H7's to your preference, be it LED's, night breakers or whatever before you fit them to the van just because it's easier than trying to replace bulbs in situ later. There's loads of threads on here providing advice about bulbs and H7's so have a read through while you sourcing replacements.
And don't bother with aftermarket H7's. They will probably be inferior to OEM and may mist up if not properly sealed.
Finally when trying to determine if a light for sale is H7 just look at the main and dipped beam reflector. In H7's the reflectors are the same height and have an extra lens next to the indicator lens (DLR). H4's have a larger reflector on the outside (dipped) than the main beam. Hope this helps.
