How to rewire install fuel pump relay mod Wiring in the 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. How to Test Fuel Pump Relay | DoItYourself Generally there are four pins (terminals) on the fuel pump relay. One is for input voltage, one is the ground pin, one is the load pin that goes to the fuel pump, and one goes to the battery. To figure out which pin is which, there will usually be numbers on the bottom of the relay that indicate the pin positions, or you can locate a wiring diagram from your relay’s specific manufacturer.
