Help with understanding Blueprints and bin files

Hi All, I'm trying to adjust locomotives on the Pacific Surfline Route. I have the air flow working correctly for the most part and the needles on the gauges are correct now. I am having trouble finding a way to add the second red marker light to the front of the F59phi and I also noticed that there isn't a "Distributor" section in the J59 simulation.bin file. Has anyone corrected these little thing or can help me do it myself. I have no problem editing files.
Thanks
John
