Things You'll Need:
- Pliers
- Phillips-Head Screwdriver
- 12V 30A Horn Relay
-
Step 1
Pop the Odyssey's hood and engage the parking brake. Disconnect the negative battery terminal located on the driver's side of the engine bay.
-
Step 2
Locate the horn relay mounting on the passenger side strut tower. The strut tower is a metal grounding above your tire. Remove the old horn relay and disconnect the wiring.
-
Step 3
Install the new relay using the existing wiring. Mount the relay and install the wiring. Reconnect your negative battery terminal. Test your horn; if the horn still does not work, you may have a short in the wiring, which requires a visit to a professional.
