Got my new NRG hub and quick release, with my new Sparco wheel. Problem is, no screws to mount the wheel with. Anybody know where I can get six of these?

Also no instructions whatsoever, so doing the wiring by the thread in the faq. But I'm stupid when it comes to wiring. From wheel to qr I should have 2 female plugs, but I only have 1. I have a yellow female and a black male. So the yellow female should go to the male on the horn button, which leaves the black male(ground) going to the ground ring that is also a male connector. Do I just use a male-male connector to fix this, or am I completely wrong?
