To replace a Honda relay, using the proper tools is important. Gather the necessary tools before beginning the project:

  • New relay
  • 15- to-30 watt soldering iron
  • Rosin solder core
  • Solder wick
  • Desoldering iron
  • Small flat-head screwdriver

    After gathering the tool, locate the old relay to begin.

    1. Pry the main relay loose
    2. Using the flat-head screwdriver, carefully pry off the relay. Do this by prying the screwdriver between the relay and the wall flap, and use the desoldering iron if necessary.

    3. Pull the relay off
    4. When all sides are loose, pull the relay straight off to remove it.

    5. Heat the terminal
    6. Using the soldering iron, once the old relay has been removed, heat the terminal and apply the rosin core.

    7. Clean and inspect
    8. Clean and inspect the solder. Use steel wool and inspect for any imperfections in the solder.

    9. Insert the relay
    10. Insert the relay by snapping it into place.

    Properly installed, the new relay should last from seven to 10 years, and some relays will last close to 20 years. Using quality solder will make the relay last longer.
