Hella dual tone horn brackets

Hey guys I got a brand new 2015 TRD sport and I'm not really interested in drilling holes to mount horns. I plan on keeping my oem horns and running both sets.I'm curious to see as how people have mounted them behind the grill. I have a huge work shop and I'm going to end up making a bracket for them but I'd like to see how you guys have done it . So post some picks and give he some pros and cons
Thanks

 

I haven't done it, but would love to hear the video when you get them all hooked up

 

I just went through this with a set of Hella Sharptones, and could not find an easy no-drill way to add a second set of horns. I put them in the location of the factory horns. You could move the factory horns to the two existing holes on the driver's side fender and extend the wires, but I wasn't able to do that, since I have my aux fuse panel located there.
