  1. Ordered since I didn’t feel like ordering the connectors and wires to attach a led … Ordered since I didn’t feel like ordering the connectors and wires to attach a led light bar on my truck. They aren’t weatherproof, but make a decent seal for use in an engine compartment. The wires are adequately long and having the wiring diagram on top is helpful. They also interlock, since I used 2 relays together for my project. I might even replace the existing relay I have with one of these so all 3 will lock together. Wire is also adequate for the rated amperage since some…

  2. Works Great I wanted to install an electrical supply to the back of my riding lawn mower for a spray trailer I have. The manufacturer offers a kit for this @ about $60.00. I got the factory switch for $12.00 and this relay for $4.00, the wiring and connectors I keep on hand, and 2 hours later I had my power supply ready to go. This relay even came with a wiring diagram. For those who don’t know, you can use a relay to open a circuit as well as close one…you can use it to stop power as well as supply…

  3. Perfect for isolating low power switch circuits from the high power wiring required for large light bars. These have worked flawlessly. I used them to isolate the low power, 5 amp, circuits running to my switches from the high power, 30 amps, required for the 52″ light bar I added on my Yamaha Viking. I liked how this worked so well I used them to isolate other circuits alsol. I could run smaller wire to the switches and keep the power wiring centralized by mounting the relays under the hood close to the battery.
