female connector for fuse box

[tucsonjwt]

I need to connect a circuit for my gear vendor to a circuit that has power with the ignition on. I found an open slot but it looks like it needs a female connector end. The slot in the fuse box is "L' shaped. Where would I find a factory style female end connector/pigtail? It is hard to see but it looks like it has only one brass spade terminal in the fuse box cavity, and I have only seen female end pigtails which don't look like they would fit into the L shaped slot cavity. Thanks.
