What are you using to crimp them. non-insulated you shouldn't be using the cheap crimper that autozone has. Get a klien crimper like this.

The toothed crimp is what you use on non-insulated. Use fully closed, full circle, butt connectors too. Any good electrrical supplier has them. Not sure what Napa sold you. Been using the same crimper for 10+ years.

Back to the thread... Nice on the car @72bluNblu

That's the same crimp tool I've got. The Napa connectors are fully closed but you can see how wafer thin the material is. It took zero effort to make the crimp, and it still broke through. It not an automotive crimp, so I'm hoping it'll be fine. I definitely won't be buying these connectors again though.
