Review on Long-Lasting Posi-lock Connectors, 18-24 Gauge, Bulk Pack of 20: High-quality Electrical Wire Connectors for Hassle-free Installations by Jason Bell

I bought these connectors to install a new head unit on my truck. You usually have to solder or crimp the connections, but I have no soldering or crimping experience on this. I bought them on Crutchfield's recommendation. I spent 30 minutes hooking up a DVD/Navigation unit to the wiring harness in my house, hooking it up to the factory wiring harness in the car and it worked flawlessly. Every speaker, every connection and every module worked exactly as planned. They are very small and take up very little space. I would recommend everyone to install.
