Where is the horn relay on a 86 Chevy S10 located?

The horn relay location on a 1986 Chevy S10 is under the hood, typically in the fuse box or relay center. However, the exact location within that box varies slightly depending on the specific trim level and options.

To find it:

1. Open the hood: Locate the fuse box/relay center. It's usually a black plastic box, often near the battery or firewall.

2. Consult your owner's manual: This is the most accurate way to determine the precise location. The manual should have a diagram of the fuse box/relay center labeling each relay and fuse.

3. Look for a relay with a horn symbol: The relay might have a horn symbol printed on it (a stylized horn or the letter "H").

4. Check for a wiring diagram: If you can't find it by visual inspection, a wiring diagram for your specific truck's year and model will give you the precise location and circuitry information. You can often find these online or in repair manuals.

If you can't locate it using these methods, a local auto parts store or mechanic should be able to quickly pinpoint it for you.
