| I have a new to me pickup (2006 Ford) and it will not power my trailer. The lights work and brakes work but not the 12V. I know that the trailer is working properly as I can hook it to another pickup and it works as expected. Any suggestions on how I go about diagnosing the problem? |

Location: Arkansas | On a 7 way plug, on the truck, with the notch out at the top, your constant 12v hot would be at the 5 o'clock position. Test it with a test light and see if it is hot. If not, run by the Ford place and see if they have enabled the charging wire under the hood.

Location: Williamsburg VA | On a ford the key must be in the on [run] position for the 12v to be powered. |

Location: White Pine, TN | skippy is correct, your key must be on. BUT, go to the bottom of the Home Page here and you'll see the corret wiring diagram. The hot/recharge line is at the 1 o'clock position on a 7 way plug. |

| Thanks for the replies. I think I have it figured out, I need to add a relay for it to work properly. |

Location: Arkansas | We had a relay put on our Ford, the 12v is always on, now. And yes, look at the diagram on the home page for the 7 way wire, paying particular attention to the male vs female and the orientation of the notch. |
