Question

Confused as to how to properly wire horn relay. I've already melted the pink/black key buzzer wire in the steering column!! Fortunately I had a spare column harness.

There are three terminals on the bottom of the relay. Two of the terminals read 12 volts with key off. I believe the horns (dark green) should be on a hot terminal. But what about pink/black and the black wires.

Could someone please explain?

Try looking thru the tech articles on this site, the guy really knows his chev. wiring.

Mad Electric site

The following link goes direct to Chev. wiring.
up front wires on Mad Elec. site

That gives you a good idea of the concept behind the original wiring. Here is a pic of the master wire routing from the AIM book which you should have for its great info. Blow up the photo a little and it shows the horn relay and wires as they should be.

You might try downloading this Horn Operation Diagnosis paper from the www.corvettefaq.com websight:

http://www.corvettefaq.com/c3/HornOp...osis07JL03.doc

GM was pretty good at using common wiring colors and using the same concepts for mechanizing various electrical circuits.

Hope this helps.

There are three plug-in terminals on the bottom of the horn relay; two next to each other, and one by itself. The one by itself (inboard as mounted in the car) is for the black/pink wire (key buzzer). For the two together, the one closest to the rad support is for the black wire (horn ground from the horn button), and the rearward one is for the green wire (12V to horns).
