Hi, a friend gave me a set of musical air horns and i want to put them on my car.

I know that i need to use a relay but what gauge wire should i use between the battery and the relay and the relay and the compressor?

Cheers

Jon

hmmm.....well, just to be on the safe side, i would use no less than 10ga-12ga wire into term 30 on your relay and on term 87 out to your compressor.
