Green is temp sender, blues (light and dark) are parking lights and brown/tan are side markers. See bottom left in picture.

If you don't have a 72 factory chassis service manual, download one so you have the factory, year specific, schematics. There were changes over the years and it will also have the emission control wires missing from the generic schemaics so often used as references.
