First off. Happy Birthday United States Of America.  Sometimes is/been a rocky road, but still we keep on trying.

Now for Vanagon content.  With all the recent relay talk, I think I will finally install headlight relays.  But I have a question.  My Westy (the Bus) is an '87, but I changed to the '84 2 headlight system due to the crappy light I was getting from the original 4 light system.  Not knowing how far back wiring changes are for the different models, I wonder which relay system I would use, and the best setup.  I heard someone's name mentioned as opposed to the usual vendors.  Next, how do I determine the date of manufacture of my current generation Golf engine?

Thanks for all, and enjoy the Holiday if you have one.
