Omega Train Horn Help!!

I have an Omega three horn setup with an “AC-200” compressor and tank. For the life of me I can not find anything online about the wiring diagram so I can install this. Does anyone have a diagram or can point me to a website to get one? I have looked and nothing comes up for AC-200 compressors, other than buying one. I would hate to just wing it and burn up a relay, compressor or much less my truck wiring. I am planning on installing this in a Ford F250 SD. Any advice on wiring and locations and tips would be greatly appreciated.

thanks
