First post, but hopefully a useful one. This was a PITA to get out of Ford. I needed this info for installing a LOC behind the radio for the addition of an aftermarket sub. They gave me the diagram, but I discovered there's a typo. In the tech service document it shows the FRONT LEFT - as being Green/Brown, but that's incorrect. FRONT RIGHT - is Green/Brown. The actual FRONT LEFT - is Gray/Brown. Below are all the color combos as well as pin locations on the attaching wire harness. It's a 24 pin connector with numbers on the back of connector.
