2006 Ford F-150 Electrical Issue

Difficult to fine on-line free. I use to run into obtaining electrical diagram problems in the past. In finally subscribed to ALLDATADIY for repair info on all my vehicles. A one year subscription is about 25 bucks and is vehicle/VIN specific. The subscription has complete wiring diagrams which are wire color coded. They will also show the location of all relays etc. Twenty five bucks is well worth not spending hours trying to trace wires.
