We bought a 1982 vette and found that the front clip was replaced and when they did replace it they did not put the horns back on. We have not been able to find the horn wires that should be around the steering column that would have attached to the horns. We want to put horns on it and need to have an idea where the wires come out of the car by the steering box. Anyone with a diagram or instructions I saw where one article said two black wires came out and one went to a theft alarm but can't seem to find any wires from the horn button to under the hood. Any info would be appreciated.

The AIM shows these. The horns mount at the very top of the fender skirts out front. If memory serves, the wiring comes with the forward lamp harness on each side.

You are looking for DARK GREEN WIRES.

Assembly Instruction Manual


And you might also want to obtain a Factory Service Manual also. NOT a Chiltons, Haynes or Mitchell...get the correct book from a major Corvette supplier. There is more detailed data in the GM book than the others.

There should be a horn relay (or at least the connector for it) in a three-wire breakout to the left and almost above the fuse box--yes it's a pain to see

The three wires leading to the horn relay are: Orange--power from the CTSY circuit. Black--ground coming from the steering column and contained in the "harmonica" connector whose other end is the turn signal switch. Dark Green--this is power to the horn.

The Dark Green wire is energized (+12V) by the horn relay when the horn button is pressed. The horns are grounded to the chassis so there's only one wire feeding them. From the relay, the Dark Green wire routes back behind the fuse box to the big connector that goes through the firewall. After that it follows a large bundle of wiring heading forward and sort of tucked up under the left (driver) fender. It will break out in the front left of the car ahead of the radiator. The single wire simply chains via the connector on the first horn to the second horn.

Testing the circuit is easy. Make certain you have +12V (constant) at the orange wire leading to the relay. Make certain that you get ground at the black wire leading to the relay when you press the horn button. If good so far, make sure you have +12V at the dark green wire with the relay installed and horn button pressed.
