I found this on YouTube. It appears that the yellow bands are on the driver side. If you fast-forward to 5:24 you will see. I have a spare pair of front springs and they appear to be identical in twist where they start and stop. I don't know why Toyota has 2 part numbers when they look to be the same. The OEM springs I now have on my car are re-painted black, so I couldn't reference them.
