I got lazy and installed some of these connectors to two of my cars. Last Saturday I had the worst electrical night mare ever, the car kept shutting off and turning on. It was close to Halloween, but really? I was going nuts changing wires and replacing batteries. I got home and noticed the connector was spinning. It wasn't maintaining a connection, so it caused it to shut down, and then later come back on. Needless to say I ordered some solid connectors from amain immediately. I really hope this solves the gremlins for awhile????
