Replaced the actuators, although my originals were still working and I still have them boxed up and stored away. All of the hoses were replaced including the vacuum hoses that penetrate the firewall and connect to the headlight switch. Repos were good and properly color stripe coded. What I view as the potential weak link in the system is the relay valve. Mine is original, still works fine, but it would be a very difficult item to replace. I have to admit, I haven't looked in a whiile, maybe others have better/newer information, but the repo relay valves that I've seen in the past were not correct - service replacements that had a differing appearance.
As far at the straps, I tied down both the vacuum hoses and headlight washers in more places than the AIM showed primarily because from time to time in the past I had issues with the doors sticking in the open position. It was difficult (at least with my ride) to keep the vacuum lines properly secured with just the original tie downs and core support clamp. If the vacuum hoses slip out place, they can interfere with the doors as they open resulting in the doors binding agianst the vacuum hoses and remaining stuck open. So....when I put everything back, I tied them down in a few extra places to ensure that there would be no interference with the operation of the headlight doors.
One more RS question. Did you replace your springs on the door mechanism? I did not and think that I may have a weak spring on the passenger side. The door opens and closes but is slow and I have good vacuum. Sometimes a little nudge gets the passenger side to complete its cycle. I am also going to recheck for binding and lube everything but I have done this once already and had no binding and the door opened good.
