Review on 💡 ONLINE LED STORE - 1 Pack of 5-Pin 12V Bosch Style Waterproof Relay Kit with Harness Socket, 12 AWG Hot Wires, SPDT, 30/40 Amp - Ideal for Automotive, Marine, Boats, Auto Fan, and Cars by Devon Leach

I'm not a professional auto electrician but I know a lot about it. I wanted the optional USB port to work in ignition key mode in position A with some sort of power off delay. The relay is necessary to avoid too much power consumption and losses. Of course, using a waterproof system in the car is always preferable. The online LED shop provided exactly what I needed and the system works flawlessly. I am very happy with their offer and had to order it again as my friends are putting a lot of pressure on me to make this connector for their cars too. The only thing I had to change is the sensor of the connected cable, since the original comes with a small caliber number that is too thick for a small consumer. With a little effort you can get the job done, but I think it's much better to just provide the relay with the contacts needed, leaving the customer free to decide what gauge of wire is right for the task. Good value for money. On time delivery.
