About how much current is enough off the steering wheel switch?
Regarding tapping off the batt, easier said than done. G4’s battery is in the rear starboard side. Anyhow, I’d rather tap into the fuse box.
I’d investigate the fuse panel under the steering column. There is probably a 12v constant hot circuit there that you could piggyback with an add-a-fuse type device, then use the OEM horn positive wire for the trigger.I'm looking into upgrading the stock horns. Is anyone familiar with where I can cleanly tap the relay into for the 12volt power?

I added four Hella Supertones to my Tacoma many years ago. It sounded like a freight train and certainly command more attention on the road. Well worth the effort.
