86 Econoline 150
Random dangling wire labeled 79?
Severed fuse wire
Wired red wire that cuts into orange passanger side firewall.
Above control center with single working switch?
Radio before being removed
In the back of the van. Think this may be operated by auxiliary power. The van had a battery in the rear as well.
More overhead lights
Overhead lights
Use the factory wires (what's left of them) and go from there
Your illumination wire is light blue with pink or red (start there) it goes all over starting at the headlamp switch
Possibly upgrade the fuse panel
Those old ones sometimes short out behind where they bolt together at the bulkhead (we used to take them apart and remove the burnt wire
then run a new wire thru where the burnt one was removed.
Good luck
Fix one circuit at a time and use a junkyard harness for wire (so you get some of the correct colors)
I'd start with an original EVTM or "book of schematics" that are sometimes found on eBay in gently used condition---you could use that to correct any problems with the factory wiring. If this is a cobbled up mess from a previous owner or a slip shod converter that's another issue not so easily solved without seeing it all in person.
Good luck with this---seems to be quite a project!
