There is a tool for these but if you are careful you can crimp them with pliers if you are unfamiliar with them do a trial first maybe. I would think the Blue one is probably the size to chose from the pack.
If you have a local agricultural supplies shop most stock these or any auto supplies store.


I have had too many failures with insulated connectors. My Mentor (old Brit car mechanic) suggested I use un-insulated connectors and shrink insulation. This is what I am using and NO FAILURES. You do need a crimper for un-insulated connectors however.
