JP,
Were these easy to hookup while keeping the OEM's? I thought there would be only on 12 volt pin connection. Do you have any pictures and where you mounted? It would be nice to use the regular horn on the steering column versus having to run a relay switch. Must be extremely loud if you use both the OEM and Nautilus.?.?

Thanks for the replies everyone.

 

The horn basically is mounted in the same location as the OEM’s but on the opposite side (drivers side) I used the instructions that came with it to hook it up. It has its own fused power wire coming directly from the battery to the horn via the relay. How I got it to work off the steering wheel with the OEM’s is to tap into the positive (+) wire on the OEM horn to power up the relay. This way you’re not putting an excessive load on the factory wiring. It is LOUD though but I always use it prudently and only when I have too

 

Thanks, JP. I know what I'm ordering today.
