Step-by-step guide to fixing your 1968 Chevy C10 horn wiring
Step 1: Disconnect the battery
The first step when working on any electrical component in your car is to disconnect the battery. This is important to prevent any electrical shocks or damage to your car’s electrical system. Locate the battery under the hood of your Chevy C10 and disconnect the negative terminal.
Step 2: Locate the horn and relay
The horn relay on the 1968 Chevy C10 is located on the firewall just above the brake pedal. The horn itself is located on the steering column. Identify both of these components and inspect them for any signs of damage or wear.
Step 3: Test the relay
Using a multimeter, test the horn relay to see if it’s working properly. First, set your multimeter to the continuity setting. Then, place one probe on the negative terminal of the relay, and the other probe on the positive terminal. If the relay is working properly, the multimeter will beep. If it doesn’t beep, the relay needs to be replaced.
Step 4: Replace the relay
If your multimeter test indicates that the relay is faulty, remove it from the firewall and replace it with a new one. Make sure to connect the wires to the correct terminals on the new relay.
Step 5: Check the wiring
Inspect the wiring running from the horn button on the steering wheel to the horn itself. Look for any signs of damage or wear. If you find any damaged wiring, cut the damaged section out and splice in a new piece using wire connectors.
Step 6: Reconnect the battery
Once you’ve completed all the steps, reconnect the battery and test your horn to ensure it’s working properly. If it’s still not working, you may need to replace the horn itself.
