Has anyone wired airhorns to the auxiliary switches? I'm looking to install the MotoHorn 3.0 using the auxiliary switch to turn on/off the MotoHorn between the OEM horn and MotoHorn. Ideally, I would like the steering wheel horn to operate both independently. When the auxillary switch is in the on position, it will activate the MotoHorn and off position, the OEM horn. I'm stuck on wiring up to the 5 post relay to get this to work. If anyone can post a wiring diagram, it would be greatly appreciated.

So yes and no. I installed a switch that when on, will trigger both the motos, and the stock horns from the steering wheel horn button, and when off, will only trigger the stock horns. I've got pictures, but i think I mightve posted them already.
