It has become apparent to me Ford no longer follows the rest anymore. My trailer lights work with all my other trucks but with this F150. Let me rephrase, it works, but the constant hot/live wire isn't the same, hence I have no interior lights inside my enclosed trailer. Which one is always hot, or the color, so I can by-pass to connect at both ends, the receiver and trailer. The center pin on all my other trucks are the hot, but apparently not this Ford..

 

The center pin is for the reverse circuit, only hot when it's in reverse. You do have to install the relay for the center pin to have power though.

The 12v constant (w/ignition) wire is the Orange one

 

You've come thru- again my friend! Thank you. If the orange wire is keyed hot, are you saying a relay is needed to make that pin hot, with key off?? On my other trucks it's constant hot, so when the truck is off I still have power in the trailer.

 

The relay is not needed for the orange wire/pine, just the center/reverse pin. Let me look again, I thought what I was looking at last night in my wiring manual showed it ignition hot, maybe not

 

It is hot all the time

Here is each wire
YE...................L turn
BR-WH.............Park
OG...................Power................Hot all the time as you though
DG...................R turn
BK-PK...............Rev...................Only hot off relay, while in reverse
DB....................Elect. Brake........need a brake controller for this one
