What are the pins on a fuel pump relay?

The relay should have 4 pins on it. They are usually labeled 30, 85, 86, and 87. Steps: 1. Wire pin 85 of the relay to the 12v supply wire from the stock ECU that you just cut. This 12v wire will now energize the relay to turn on. So now instead of the stock ecu energizing the fuel pump, it will energize this relay. 2.
