+ 100 for anyone that uses posi-taps instead of those horrid Scotch-locs!
Just an FYI.
The entire Motorcraft plug and pigtail catalog is online (and probably archived here on the forum too)
Plugs and sockets are laid out by number of connectors.
There are diagrams and pictures of their configurations.
Once you find the right Motorcraft number any auto parts store can cross it to Dorman or Balkamp or BWD or whatever...
