Were do I find the Wiring Diagram from Galaxy Fulcher 2007 Caravan to Ford Ranger 2010


http://www.narva.com.au/products/browse/wiring-diagrams

use a volt meter to work out which light is connected to which pin on Ford Ranger trailer plug . Hopefully it corresponds to standard trailer wiring diagrams. Test each wire could also use a light bulb with two wires soldered to it or a 12v dc probe.

Hello Carol, The 7 way is for use with a brake controller and/or a trailer that has electric brakes. The 4 way flat is a basic trailer plug connector.
Connect as follows:
Green wire- Connects to the vehicles right turn wire harness & provides brake light and right turn signal on trailer.

Yellow wire- Connects to vehicles left turn wire & powers brake light & Left turn signal on trailer

White wire- Ground

Brown Wire- Tail/ marker/ license plate lights

The Blue, Red & Purple wires on the 7 way will not be used on the adapter, those are for brakes.

I hope this information is helpful.

No trailer right turn signal or brake light


Hey Boon,

The pinouts for a 7-way plug are as follows:
Seven wire Trailer plugs:

Horse, stock or utility trailers:

White = Ground - 1
Blue = Electric Brakes - 2
Brown = Tail and clearance lights - 3
Black = Battery, aux power - 4
Yellow = Left turn/Brake - 5
Green = Right turn Brake - 6
Orange or Purple (not both) = Auxilliary or Reverse - 7

Recreational Vehicle:
White = Ground - 1
Blue = Electric Brakes - 2
Green = Tail and clearance lights - 3
Black = Battery, aux power - 4
Red = Left turn/Brake - 5
Brown = Right turn Brake - 6
Yellow = Auxilliary or Reverse - 7

In both cases 4 is battery and 7 is reverse, aux or not used.

Double check your wiring using these lists as a reference.

Wiring diagram


If you are going from a 4 pin on your trailer to the 7 pin on the truck. You need to go to parts store or a department store (ex Wal Mart) and look in trailer section and find the adapter. Thats what I did. Also Remember if your lights don't work on trailer, check the plug to make sure its tight or check the fuse under your drivers side rear seat for that fuse box.

Installing a 7-pin trailer towing recptical on a 1991 Ford F150.


I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.
