At the multifunction switch, terminal # 14 is a Green wire. Ground it to test if the taillights comes on.
Replacing the switch (item # 4) is not too difficult as it can be replaced separately but test to cinfirm it is bad first.
The lights arelinked to the BCM so it is possible you have a faulty BCM.
