Does anyone know of a "free" wiring diagram for a 2003 Ford F-250 Super Duty pick-up?
I am running an Air-Horn set-up and want to play with hooking it into the factory horn actuator (on the steering wheel).
The intent is to have a toggle that allows me to cycle from the factory horn to the Air Horns.
Also, where's the preferred place to tap into for a hot wire that is tided into the ignition (only on when the key is in)?
Any help will be appreciated.
Here's a pic of the set-up thus far... still have a few things to do on it.
