I have a 2006 v6 Mustang that i bought recently for my son. Everything works fine, except we have this issue where the drinker side headlight comes on at random times while the car is off and stays on (which kills the battery) disconnect the battery. I have checked the connector and the positive wire is getting full voltage at all times... car off, keys out... I am in need of a wiring diagram for this car so I can get an idea of where to start tracing out the issue of where it's getting...

One headlight on when car is off
