Review on 🔌 Metra 12V 30A E-123 Tyco Relay Bay Installation - Enhanced SEO by Jay Campbell

Not much to say about that. If you know what it is, you must know how to use it. I have a few on hand, I always seem to add headlights to my cars. Buy a plug for it instead of using separate connectors for a cleaner install and no hassle of reconnecting if you need to replace one. Instead of connecting it as shown in the diagram, you should connect the switch wire to 12+ and turn on the switch. ground connection. So you only have one wire going to the dash, and that's ground, not hot. Connect the other side of the switch to a suitable ground. Much safer and easier.
