Steering Column Harness Wire ID

[boomer632]

Replaced my original 69 floor shift non tilt with 69 tilt, Have an issue when I plug in the black harness and insert ignition key, horn activates. Basically the horn is operating my key reminder / door open buzzer. Im looking to identify what the last 4 wires in the column plug do. This pic is from the non tilt colum which worked fine.
