Hi,
Maybe an unusual question:
I have a van that has separate amber turn indicators and separate brakelights

It has an RV option package, and I found at the rear of the chassis 2 round connectors, one larger than the other.
Thought I would be able to find which wire is what, but not quite!

As I live in Europe, I must have separte direction indicators and brake lights on the trailer too.
I found the 2 wires which give me the indicators, but then found that when applying the brake, these same 2 wires get also voltage, just as is normal on an American set-up.
My Chilton manuals is not very helpful, as it gives no schematic and in the text states just to buy a trailer connection kit........
Following facts:
large socket has 4 thck wires
White = ground
Red = 12 volt with ignition on ( (for trailer battery electric brakes???)
Blue = ??
Black = ??

small socket has 4 thin wires:
white = ??
broun/white line = tail light
green = right dir. indicator, but also brake light
yellow = left dir. indicator, also brake light

Any way I can use these wires for my purpose?
What are the 'unknown ones ' for?

If not possible, I will have to run wires directly from the respective light units, but that is not my preferred option.
Thanks for any advise.

Oh yes, it is a Ford econoline 93

 

The blue wire is for the trailer brakes ( but on small 6 pole it can be backup lights ), white is always ground , if blue is backup lights than black will be the trailer brakes , yes the red is auxilary power for trailer battery ect.

 

IF the European color coding is the same as here in the States, White is ground, Brown is marker and tail lights, Black is auxillary battery charge for a on-board battery on a trailer, Red is power feed to 12-volt accessories on the trailer, Green and Yellow you already have ID'ed. Blue is for the trailer brakes. I hope that clarifies the color coding for you.

Since your vehicle has amber directional signal lens and red brake lens, you will need a TAILLIGHT CONVERTER to go from the vehicle split circuit system to the trailer's single circuit system. They are available here from practically any parts store or RV dealer.

Since you can get a Chilton's manual, surely you can purchase a Haynes manual, can't you? The Haynes product has quite complete wiring diagrams with circuit name and number, component location, wire color, color changes, and splice locations.

 

When I asked you about the availabilty of Haynes manuals in Europe, I forgot to mention you can access Ford wiring diagrams online from www.motorhaven.com. I have many people say motorhaven has anything for everything! I hope that, too, will be of benefit to you.

 

Thanks for your interest and response;

Trailers, like vans and cars must have amber turn indicators, and the connectors are totally different (7 pole: stop/tail left/tail right/indicator left/indicator right/ground/rear fog/
As my van has separate amber turn lights, I thought that the trailer connectors would have that too, but I figured now that this is not the case.
I just need to take the power directly from the respective lamp connectors and take that to the 7 pole socket.
You may think that 7 pole socket is already large, but the Germans have developed a new system several years ago, with a 13 pole connector!!!!!!!
For travel trailer light and (house)battery charge and more
In Europe electric brakes are extremely unusual, and only used on the rare US import traveltrailers. Hence for that reason no battery is needed.
Re: the Haynes manual, I can get this sent by a friend in PA. The American manuals are not available in our country, never seen them.
Thanks again for your response,
