almost certainly the 6 way is the same. One of the tell-tale signs is the rib down the side of the connecting part of the connector (the bit that pushes into the mating half, if that makes sense).
So to be clear here, what you need is the connectors shown in your picture (and the link Kev has given), not a mating half to what you've shown ?
If so, i'd buy them from the link Kev has given as the prices are fairly sensible (I've not used them before - good find !).
Don't forget to buy the cable seals as well as the crimps.
You might have to get a bit inventive on how you crimp the cables because your not going to want to buy a crimp tool, it just wouldn't be cost effective.
Have fun
