I have done extensive research on the topic of an alternative for the vacum system. Someone posted in 2000 about using Lebaron motors. I am sure the system will work but I have not been able to find out if the limits can be adjusted. The individual that did the system said it worked but I am wondering if the headlights opend and closed all the way, if not how can they be adjusted? Someone else posted in 2003 about using Celica motors with a similar plan. This motor supposedly automatically sets the limits, but I am not sure how. I have had no luck contacting either people. If you have tried either of these system or have a way of adjusting the limits on a system in use, please contact me. I am bound and determined to figure this out.
