So sorry I could not responsed earlier but this what I did.
You might want to try this. It's a trick I've used on the last 4 Ultras I've owned giving better night riding visability and it allows your passing lamps to stay on in both high and low beam mode.
HEADLIGHT TRICK
Open the left handlebar switchbox, and free the dimmer switch. There are three wires going to it: blue, yellow, and white. Cut the yellow wire about 3/4" from the switch, and tape or heat-shrink this stub. Now, simply splice the yellow wire onto the blue wire, insulate it, and put it all back together. Be careful not to pinch any wires when you tighten up the switchbox screws. Now when you switch to highbeam both high and low beams will stay on giving you better visability and as long your dash spot switch is turned on your passing lamps will also stay on with either low and high beam too.
now I just did a search and I saw someone else also lost the opener function. Like you said the high and low beam works fine with the passing lamps but the opener in not
