I had to dig all the rubber out holding the wires in. I will say, if I was smart, I would have just added a pin 5 and tapped into the pin 6 wire, but on the first one I was just trying to see if it worked. I didn't feel like pulling it back out and adding the pin and wire. One last possible issue which I have not come across yet is I've read other posts where the car will detect a high voltage and shut the high beams off. You wont have high beams until the car is restarted. To fix this, you can add a relay, however I have not had this issue.
I tried the same thing you did, moving pin 6 to pin 5 but on the headlight harness, and still no high beams... I wonder if I should add a relay or tap into the wire from pin 5?
