You have to buy pins and connectors seperate. I cant remember the name of the company but I have bought them before, I will look at the packages when I get home and post if no one else has. They are available in 1,2,4,6 pin configurations and the plugs come in male/female and come with gaskets as well. I will never do any automotive electrical project with out them from now on. They give such a professional installation. Kinda pricey but worth it in my opinion. Oh you also need a special tool to crimp the pins...i always solder mine as well just in case....better safe than sorry on this one. They also offer a special tool to release the pins from the connectors if needed.
PM me if you need more info. Thanks,
