Today I completed the horn toggle switch wiring in the overhead console. The regular horn button in the steering wheel now activates either the OEM horn or the electric air valve for the air horns depending on the position of the horn toggle switch.
Next I connected the in-cab digital pressure gauge to its sending unit in the air system's front air manifold. Once done I also wired the pressure switch into the compressor slot on my custom Bussman relay box ... and pre-ran a 12v output line from the Bussman box near where the compressor will be installed ... such that hookup will be a snap when installation time comes.
Last, I removed the bracket that supports the red plastic box which normally houses the connection between the alternator and positive battery terminal. Once done I shifted the wire positions to make room in that space for the York 210L.
More hard line plumbing, tomorrow...
