Hi Germ
Ive done these as well, theres a reverse type locking barb on the connectors that when you slide the terminal and wire into the plastic plug pops up and locks the two together. You need to depress this with a jewelers screwdriver and it will pop out. We warned it can be frustrating and try not to mullah the plug or terminal. The barb is almost always on top of the terminal so you slide the screwdriver in from the back (wire end) of the terminal and pull the whole lot backwards out of the plastic plug.
I have bought all my connectors from the USA from
www.cycleterminal.com, good and fast delivery to Down Under too. Buy the correct cheap crimper also and you will not regret it (our work electrician confiscated mine it was so good).
The terminals you need are 1HB-050 Nt Male and 1HB-050 Nt Female (well they were for my 05)
I have pictures but am away from home and cannot upload them sorry
