lost stars for no instructions in the box or on the website. As soon as I found the instructions for a similar toggle switch, I figured it out. The blue LEDs for the switch are connected directly to the battery, so are ALWAYS lit. I removed this connector because I found the switch LEDs to be bright and distracting. Once installed, the switches work great. They are durable and have a satisfying click. Port number: 1 - n/a 2 - battery power 3 - power to lights 4 - n/a 5 - n/a 6 - toggle switch LED 7 - ground 8 - ground
