Does anyone have or know where I can find a wiring diagram for the audio system in a 2007 Ford Fusion? I have the stock single CD stereo installed and I just bought a new stereo I want to install (Pioneer AVIC-X910BT). However, pulling the connections off the back of the old stereo there are two clusters of cables that snap into the back and I have no idea what is what. The new radio I bought also has built in GPS so it's also asking for a few additional connections that I'm not sure where to find: -Car Speed Signal Input -Power Supply Cable for the On/Off Status for the Parking Brake -Reverse Gear Signal Input - Which looks like it's just the Backup Light Lead. Any help would be appreciated.
