I'm using quick connects to wire up my control panel and had a question about them since I've never used them before. Theres a round red plastic piece on top of the quick connect and a hole at the end.. The wire goes through this end? But on the other, metal end, there are 2 curved circular metal pieces, do the wires need to go through one or both of these then crimed down onto the connector on the switch? Like I said, maybe a stupid question but this is the first time I've done anything like this. Thanks.
