Hit up Travis over at KCAutoSound.com.
He does custom F150 installations in the Kansas City area as well as stock installations for dealers. On top of that he runs the online store.
For us F150s (and only $25 more), he does what's called "pre-wiring", where he deletes any unnecessary wires and ties them up for an easy install. He also includes custom color instructions for our trucks, making it a fairly easy installation.
I installed mine on a rainy Saturday, and he was available by phone to answer any questions I had. Very helpful (and busy) guy. Highly recommended here.
FYI you will also need a PATS bypass.
x1000!!!!! With Travis's pre-wiring and his awesome instructions its a breeze to install them, just takes a little bit of time.
I installed a Code-Alarm (CA-430 I think) model I got from him and those are probably the most complete instructions I've ever used. It even lays out what techniques to install it, not just what wire colors and where they go. You will need a test light just to verify your hooking into the right wire but those are only a couple bucks each.
Highly recommend going with him, saves you a lot of money too!
