Are there 2 pink wires in the connector (maybe labeled AHV & AHR)?

* One of those (AHR) should measure 12v when you "honk your (steering wheel) horn".

* The other (AHV) is intended to connect to & power an air horn relay solenoid coil and the air horn valve coil.

You would probably find AHV as a spare in your DC fuse & relay compartment.

It would be too good to be true that the wires were actually labeled.

NOTE: The AHV line is NOT intended to directly power the air horn motor... A relay is to be used. The spare pink w/black tracer wire(s) for that option might also be found in the DC fuse & relay compartment.

So my question is: How does the air horn work? Why is there an electric pump & a motor?
