Congrats on your good progress Gregory ! re your terminal 15 comment.. you may find it interesting to find out there are two kinds of 'key on' power that come out of the ignition switch. '15' is 'on' during starter cranking and running. Feeds ignition and engine systems like that. You've probably noticed the headlights go off ( if you have them on ) while cranking on the starter.. that's becuase they are powered by 'X' voltage out of the ignition switch. As are the wipers. If on, they also will not sweep while cranking on the starter. You can see the X contacts in the Bentley diagrams at the ign sw. a very common failure is the X feature of the ign switch stops working .. then...headlights do not work at all , except by pulling the flasher/dimmer stalk , which is powered with B+ full time battery voltage. .. if/when that happens to your van..the light failure thing ..you'll know right were to look for the problem !
