7 way trailer plug center pin?

I am installing 2 flood light bars on my rear bumper. I am wiring them to an aux switch, but I also am planning on wiring them to come on with my back up/ reverse lights.

I figured the easiest way to tap into the reverse lights would be the 7 way trailer plug (center pin wire) instead of searching for the correct taillight wire.

Can anyone confirm that the center pin in the trailer plug is for backup lights?

I turned my key to on position and placed truck in reverse and used a tester but had no power on center pin.

Am I missing something?

not sure from ford, but the industry standard is thats for batt + on a trailer (like a camper or any trailer with a batt)

What this nation needs is cleaner thoughts and dirtier fingernails...

Your Ford's center or auxillary pin (Purple wire) is for reverse lights. Check the fuse panel for missing or inop fuse. Ford uses fuses for the trailer side so even if your reverse lights on the truck work doesn't mean the RV jack does. On some boat trailers the center pin activates the reverse hydraulic brake lockout so you can back up the trailer.

Yep. IIRC trailers do not have back up lights.

If anything RedTrailers.com is a very good site for that kind of stuff and the old man that owns the business is extremely helpful.

This is the diagram right on the plug

Top: RH turn/brake
Bottom: LH turn/ brake

Top right: marking/ running lights
Bottom right: ( + )

Top left: ( - )
bottom Left: trailer brakes

Center pin: backup lights.

I'm guessing the bottom right (+) is for 12v accessory ( trailer battery)

And the top left (-) would be ground

I have power on all pins except center. And I'm stumped as of why.

Thats strange. I guess use a meter to double check.

This is industry standard.

Even on that diagram they claim center is backup lights.

Well I guess that plan isn't going to work. I guess I will have to find a wire going to one of my taillights.

Do u have a multimeter? Put ur truck in R and see if you have 12v at that center pin when ur truck b/u lights come on.
