Location: Pontiac, IL | I HAVE A 2004 HART BUMPER PULL TRAILER THAT HAD A 6 PIN CONNECTOR PLUG. I DECIDED TO INSTALL A 7 PIN PLUG TO MATCH THE PLUG ON MY 2008 FORD F350. HOWEVER, I CANNOT FIND A DEDICATED WIRE FOR THE ELECTRIC TRAILER BRAKES ON THE TRAILER. THE 6 WIRES FROM THE TRAILER ARE AS FOLLOWS: BLACK - HOT; WHITE - GROUND; RED - LH TURN/BRAKE; GREEN - RH TURN/BRAKE; YELLOW - RUNNING LIGHTS; BROWN - INTERIOR DOME LIGHTS. THERE IS NO DEDICATED WIRE THAT APPEARS TO BE LEAD TO THE ELECTRIC TRAILER BRAKE SYSTEM ON THE TRAILER. ANY SUGGESTIONS? |

Location: North Carolina | What does the black wire do ? Seems a logical choice for a TRAILER. You might apply 12 volts between it and the ground wire. See if the brakes are energized. |

Location: Pontiac, IL | I'm not sure what you are suggesting. The black wire coming from the trailer connects to the 12 volt power source from the truck. Are you suggesting that I split the black wire and connect it to both the power source pin on the truck connector and to the trailer brake pin on the truck connector? Thanks! |

Location: Pontiac, IL | Thank you for pointing out this link. I did review it. Unfortunately, it simply shows a blue wire from the trailer which connects to the electric brake system. My trailer does not have a blue wire, nor can I find a wire that seems to connect to the electric brake system on the trailer. |

Not sure where you got these labels, but I believe there's an error. What you call "Hot", will also be the battery charge line, which is also the interior dome light circuit. So- with that you have 2 wires with the same label.
As has been mentioned, would be best to take a battery and ground it to the trailer's frame (with a jumper wire/cable). Then touch each of the other wires to batt + and see what activates. Except for the white wire- which like you I think will be ground. Touch it and you'll get sparks |

If you are not going to call the Hart Trailer people...then track the wire(s) going to and coming out of the breakaway battery unit...because that should tie into your electric brake circuit
