Wiring For Backup Lights On Toy Hauler
I am trying to figure out the wiring on the 7 pin connector for my 1999 Ford Super Duty. I want to use the Ramp Lights on the Toy Hauler as backup lights when I put the truck in reverse. I have read that the center pin is used for backup lights. I have tested the center pin (truck side) and get no power when trucks backup lights are on. I can't find any continuity from the center pin to the wires comming out of the 7 pin connector even though I have seven wires? I have white,blue, brown w/white stripe, yellow, green, black w/green stripe and orange? Any idea of which color wire is used for the center posistion? I know on the trailer side it's yellow but not on the truck side...
