Waking up an old thread, but my experience may help someone else in the future. I primarily did this mod (thanks a lot OP!) to not have my new HID fogs flicker my new LED high beams. Apparently this mod helped several people to fix this particular issue. Since I was not interested in having my fogs run independently, so I thought skipping to the last step (where you connect the two wires underneath the left stalk) should be enough for me. However, just doing the last step DID NOT fix my issue. I had to do the whole mod (from 1st step till last) in order to fix my issue and have the fogs run independently.
