suggest you purchase a manual as they are invaluable when working on vintage cars like ours. It is available on CD or paper. Best money ever spent.

Nice, just color right rear turn/brake dark green.
Might confuse some folks.

Right rear turn/brake is suppose to be dark green. Left side IS yellow but you've got it on both sides. Light green to backup lights is correct.

Dark green wire is labled right before it changes colors.

Below the rectangle block (where you didn't change colors) is labled dark green, all the way back to the turn signal switch.
But yes you're getting there, just change the 'YEL' to 'Dk Green' in that one section.

Edit,
Looking back at the original black and white diagram the wires were mislabled in the section in question.
