Just as a heads up, I worked in the 12volt industry for over 8years as both sales and installation. I appreciate your candor on how you would do it. However, I have already correctly wired the compressor as well as plumbed the air lines. Everything is fused as well as ran off a dedicated 12volt switched power to save me from a dead battery should the tank have a leak while parked.

All I asked for is the wire color coming from the steering column for the horn. Reason being, the horn button when pressed creates the ground I need to close the switch to open the solenoid.
I apologize for not explaining in detail my installation or why I was needing the wire color.

That being said, Does anyone have or know the wire color for the horn button coming from the steering column?
