The Harbor Freight is the High tone version and they claim that it uses 5 amps. The Focus horn fuse is 20 amps, so I don't think there would be a problem running a high AND a low horn together without using a relay. As I posted before, my Chevy has the air horns powered directly from the stock horn circuit with NO relay.
I'm a middle aged guy, with a middle school mind.
