Hi there,

If you have the Renault end, I've got the rest. I have the pinouts for 7 wire, 6 Wire and 4 Wire, One of them will fit the bill

Plug Types/Application
7 Way - RV Trailers, Horse and Utility Trailers
6 Way - Horse, Stock and Utility
4 Way - Utility Trailers

Columns are: Color, Function, Mark on the plug.

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


Six wire trailer plugs:

Horse, stock or utility trailers:
White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Four wire plugs:
White = Ground
Yellow = Left turn/Brake
Green = Right turn Brake
Brown = Tail and clearance lights


Ground should be 10ga.
Others 14 ga

A test light and a 12VDC power source can be handy for trouble shooting
.
Best regards

All of the wires you need are on a plug inside the left corner post behind a grommet behind the reverse light. The wires you need are best tested with a test lamp to identify them as there are wires with the same colours that have different functions, but if you put the lights on one at a time you can identify them with the test lamp

Firstly you need to know the make of the towbar, then you can download the fitting instructions from the towbar manufacturers website. As far as electrics are concerned, I would recommend NOT using the secondhand electrics that you have unless you have a dedicated plug-in wiring kit as the wires were probably cut and may now be too short to use and the sockets may not be in tiptop condition, It's well worth the small expense af replacing them. The actual wiring will depend on what year and model the car is.

Don't go by colors, use a test light and find them that way, much simpler.

I assume that the towbar didn't come with a proper wiring kit as, unfortunately there is not a specific connector for the towbar wiring on the x-type, the proper Vehicle Specific Kit plugs into the rear light. There is a power connector with three pins on the left and a grey reverse sensor cut out connector also on the left. but you will either need to use a Vehicle Specific Wiring kit (about £175) or use a bypass relay system.

ARE YOU READY
L.H. STOP AND TURN ( YELLOW )
R.H. STOP AND TURN ( GREEN )
TAIL, LICENSE, SIDE MARKERS ( BROWN )
GROUND ( WHITE )
NOW THE COLORS ON THE VEHICAL ARE GOING TO BE DIFFERENT AND YOU WILL NEED A 12 VOLT TEST LIGHT FOR MAKEING SURE YOU HAVE THE WRITE WIRES FROM THE CAR TO THE TOE BAR, DON'T NEED BACK UP TIGHTS FOR THIS

the best way to wire it is to get a tail gate board off a trailer and plug it in to the towbar then wire red to stop n tail lights green or yellow to the earth what other orange or brown to indicator sum wires may differ in colur wat colour wires do u have on the towbar
