Checked I had only ordered one.
You're in Australia right?
I recall Newark Farnell is similar to Mouser and is a international company although it looks like Farnell is now element14.

Go back to my post with the part numbers and search there. It looks like they will have the parts needed and can be purchase in low quantity's. Did notice you would have to use part # 43030-0009 since 43030-0012 has a minimum qty purchase of 100. The only difference is wire size, actually after building mine this new part # would probably work better.
It looks like parts sold at element14 are of the same of mouser. If so most any connector or pins when working on harnesses like on our cars can be purchased form there. Some digging would be needed to find the right part #'s for the part you may need.
