Review on Nilight Automotive Harness Interlocking Socket by Justin Buck

Works perfectly. I used them to isolate the low wattage 5 amp circuits going to my switches from the high wattage 30 amp circuits needed for the 52 inch lightbar I power my Yamaha Added Viking. I liked how it worked so much that I used them to isolate other circuits as well. I was able to run a smaller wire to the switches and centralize the power wiring by installing a relay under the hood next to the battery.
