If you skip to 4:44 you can see an Escape with orange turn signals on the bottom right corner.
I've only seen one other example, but it was a custom job from Russia.
My guess is they cut the taillight harnesses, and tapped the high wire into the 3rd brake light, and tapped the low into the front parking light, and then ran 2 wires from the front turn signal (positive/negative) into a new socket for the signals.
They could have probably used a 1st gen Escape harness, but I don't think the BCM has a provision for separate turn signals.
