You might want to search eBay under the Manuals & Literature category in eBay Motors----look for a new or gently used factory Wiring Diagrams booklet---typically $10 or so. I see them there all the time, have purchased several for my various Ford vans and they're invaluable.
I'm kinda surprised something like this isn't available online somewhere----makes me glad I have my own reference works!
HTH
Great idea. I'll check Amazon and Ebay first chance.
This thing with the lighter losing power really has me mystified. I've had the vehicle for over a year now, and this is the first time I noticed it. I have never had to use the lighter socket before. Any idea why this might happen? bad ground maybe?
