Review on Nilight Automotive Harness Interlocking Socket by Keith Samuel

Ordered because I didn't want to order connectors and cables to mount the LED panel on my truck. They are not weatherproof but provide a good seal for underhood use. The wires are long enough and the schematic above is helpful. They also block as I used 2 relays together for my project. I might even replace the existing relay I have with one of these to get all 3 working together. The wire also corresponds to the amperage, as some pre-wired devices use very thin, poor quality wires. The wire soldered easily and made installation easy for my application.
