Great Value for the Money
I bought these as for a truck project, and thank goodness I bought the 5 pack. The wires are very good thickness, easy to understand schematics, and you can pull out the wires that aren't needed (3-4-5 PIN) to complete your project. I have connectted accenting lighting to LED Bars to this relay.
