I know I'm a noob, but I have a thought: If we could use this thread to compile all of our wire diagrams in one place it would likely benefit us all. Anyone planning to mod their car will likely need diagrams at some point, and if they're all in once place, and stickied, it couldn't be more easy.
Please post whatever wire diagrams you have access to for 99-04 V6 Mustang; starter, windows, locks, lights, ECU, ect. Paste it as an image so they're visible all from this thread. If we can stick to a format (IE, bold titles with images immediately after), they'll be really simple to search through. I'll start with what I've found through Google (which isn't much, hence the reason for this thread):
Headlight Wire Diagram for 99-04 V6 Mustang (+Foglights)
If anyone has window and/or lock diagrams, that's mainly what I'm searching for at the moment...
