How To Wire a 4 or 5 Pin Relay With a Negative Trigger Wire.
In this video, I explain why it is necessary to use a relay in a circuit. I then demonstrate how to wire a 5 pin relay with a negative trigger wire. The benefits of using a negative trigger wire on a 5 pin relay would be - one less power wire going to the relay, and not needing a power wire feeding your switch. This may be beneficial depending on what type of accessories you are wiring into your car or truck. You could use this method for a radiator fan, fuel pump, headlights fog lights, spot lights, LED lights and probably hundreds of other uses.

Pin 30 - Incoming 12v to the relay from the battery (fused)
Pin 86 - incoming 12v to the relay from the battery (fused) - Tied in with Pin 30
Pin 87 - Outgoing power from the relay to the electric accessory (lights, pump, fans, etc)
