Hey,
I know this is gonna sound pretty stupid but what exactly does a relay do?
I've used them numerous times installing air horns, offroad lights and such in my friends jeep and a few times in my car but what do they really do?
I know this is pretty stupid but I gotta find out somehow.
:lol:

Thanks,
Mike
