Yes I saw a thread here where Anderson connectors were mentioned.
So I checked their web site and the connectors look like pretty good value and with the connectors being genderless all I need to do is get an even number of each colour.
If I go for their PP15 connectors that would work. Except that means cutting square holes rather than round ones, and square holes are, well, not too difficult I suppose, just a bit more fiddly.
Hmm about IP67. I'll have another think.
