As the title states. I just test fitted the 4 air horns under the hood and the fit is easier than I thought. The 2 gallon tank and compressor will be in the back corner wagon area.
I'm sure the horn wire can be found behind the bumper. I really don't feel like taking it off. I did it once when I re-surfaced my headlight lenses but I'm lazy and don't feel like getting it there.
Can anyone tell me the easiest under hood location to tap into that wire?
It's just going to be powering an electric solenoid valve, very low current draw.
Thanks in advance. An install walk-through will soon follow.

I saw a guy in a Ford F-250 get a ticket from Katy TX police about 2 weeks ago for blowing a train horn in a grocery store parking lot. Fun to have but illegal here.

I'm also in the Katy, TX, area. Hadn't known it was illegal, but have heard a raised pickup truck rumbling through the neighborhood with a train horn. Although, I haven't been hearing it these last few weeks.
...
Looking forward to seeing the installed train horns in an Outback!
As to the question of wiring:
Since the air tank is inside the back of the car, I presume the pump is as well. Therefore, look for a connection near the steering column going to the horn contact under airbag. Or, look for one at the horn relay.

On my previous Legacy I wasn't too reckless with them. I won't use them near pets, kids, (teens are OK), or enclosed spaces with people, (like my shop).
Had them in that car for 3 years. I use the system primarily for the on-board air supply.
As far as the F-250 guy getting a summons in a parking lot. Sounds like an unnecessary place to do it. He was asking for a ticket. I've noticed that nobody expects it from a stock Subaru driven by a guy with grey hair. If there is any kind of truck nearby I can use them with relative impunity, All suspicions go to the truck.

Anyway, back to easy access to the horn wire?

The air valve solenoid needs 1 horn trigger wire only. The solenoid must be under the hood near the horns.
The compressor will be using the audio systems distribution block which is already in the rear of the wagon under the cargo cover. The compressors power is controlled by a diode isolated relay, triggered by the amps remote turn on wire. It won't be able to run down my battery if there are any air leaks.
That horn wire already under the hood, I just want easier access.

In case this gets searched later on. I found this thread which tells me wire color. (RED/WHITE) I will update if corrections are needed. Access is better than removing bumper. http://www.subaruoutback.org/forums/65-parts-accessories-performance/11421-where-s-2005-stock-horn.html

Several years ago I owned a Tahoe. It was a bit worn when I bought it and one of the two horns was out and it sounded terrible. I found that PIAA makes horns called Sporn Horns and they come in two different tones. One set is 400 & 500Hz and the other is 500 & 600Hz. If you put them together they sound just like a train horn. No complicated compressed air setup required, just add a relay.

I'm planning on putting all four on my car once I get back to doing minor upgrades.
