Hi I got both the single and double crimper's for the kit. But there is no way I'm fitting double wires in these connectors they sent for this purpose. I know its got to be something I'm not figuring out but before I shoot hole in the car from frustration I figured I'd ask here.
Here's the connectors, some for the marker lights and some for the tail lights. I opened the one on the right a little. I've watched their video a few times.
What am I doing wrong?

Thanks !
