I'm not sure what issue you're having with your lights so I attached the troubleshooting chart also. Ford also released a bulletin with a note about the circuit that says "ISSUE: The schematic on page 61 of the 1989 Mustang EVTM incorrectly shows Circuit # 14 connected from the Day/Night Illumination Relay to the Instrument Panel Dimmer Rheostat. The Day/Night Illumination Relay should connect to Circuit # 19."

Hope this helps, if not let us know what's going on with it and we should be able to point ya in the right direction
