Im installing an ammeter gauge. I know,, a voltmeter is probably better but that's the gauge that came included in the package. Anyhow the instructions say to connect it on GM vehicles to the horn relay. Where is this located on a 74 Nova?

Don't do it. Let it fill the hole in the cluster till you can get a voltage guage to match the set.

When they fail, they tend to go up in flames. My mom lost a perfectly good 79 Ford LTD which I had rebuilt the drivetrain due to an ammeter failure. the car was a total loss after the fire.

I hear you

I'd just hate for ppl to think I suck cause I can't wire it up.

Back to the original question.....where is the horn relay located?

Im not sure on the 74s but on my 71 the horn relay is right beside the external regulator. ie

on the radiator support, drivers side.
