Relay Wiring.. Electrical wizards check me..

Below is how i plan to wire the circuit for the aftermarket airhorn. I want it to only operate when the key is in the run position, i have identified 2 10amp fuses i can use to trigger the first relay, the second relay is triggered by the factory horn switch, I can pull this off the 15amp fuse or the relay right next to it for the horn. terminals are color coded to the numerical legend. Airhorn power will come from the battery, pass through both relays and hit the compressor for the horn.

 

Do i have it layed out right? Both are 12v 30A relays. I could wire in a 3rd relay which is trigged by the power pasing through both relays, and power only runs from the battery to the horn compressor through the final one. I doublt it would be worth it thou since powerloss is minimal through the 2 relays.

 

 

 

 

The horn itself is mounted on the underside of the panel right below the radiator/tranny/oil coolers. its fairly well protected and invisible unless you get under the truck. pointed sideways.. i would have preferred forward but i could find no place that would work well for that. its behind the bumper and aimed at the large frame member right there so it should spread the sound nicely as it is.

Looks good that should work.
