backup cam and reverse wire location 2011 F150 FX2?

My all-Alpine system install in underway. Got the front and rear speakers in this weekend about to start on the amp rack (2 Alpine PDX-F4's, 2F cap and dist block). Vehicle is a 2011 F150 FX2 crew cab.

The Alpine INA-910 HU will be installed after the amp rack. The only unanswered question I have at this point is the location of the rear-view camera wire and the reverse wire for auto switching to rear-cam view.

I recall reading somewhere that the rear-cam wire is in the bundle that runs under the passenger side door floor strike plate and is purple (or pink). The reverse sensor wire -- I have no idea.

Any information on the location of these and the best place and method to splice into them appreciated.
