Is it ever just "plug and play"?

I think the best solution is to get the wiring diagram from the
spindelberger website, buy a female European connector from your
favorite glider vendor, and wire it up from the lights with separate
amber turn signals and red brake signals. It's a better system, and
means you don't modify your trailer, plus then you can come get me
from a field. This will be plug and play when you get to the port. The
Euro plug has spade connectors, so if you screw up it's easy to fix.
If your car is already wired, you just have to fish out the turn
signals. Most new cars come with a tailer harness plug with all seven
wires (and more) deep in there somewhere, so then you just call the
dealer and get the trailer wire plug.

You can only do this if your vehicle has amber turn signals separate
from the brake lights. Check your vehicle.

Of course no matter what you do there will always be some turn/brake
light incompatibility between those who made their trailer US-
compliant and those who were able to make their tow vehicle Euro-
compliant. That makes for lots of fun at contests for the crew-less
set. I used to run full Euro wiring, including the plug. Now I use a
use 7-pin US plug and Euro wiring so at least someone can get a half-
workable solution if they have to tow my trailer with a US-standard
vehicle. If you ever fly crew-less it also makes sense to have some
converter pigtails to the US 4-pin plug and even the Euro plug if you
are totally anal.

A word of warning - before you start tying trailer lights into your
car's brake/running/turn signal circuit, make sure your vehicle
doesn't have a computer connected to the lighting circuit. A clue of
the use of a computer is that you get a message on the dash when a
brake/running/turn signal light is out. If such a computer is being
used, you can blow it out if you draw too many amps.

Here's a link to a previous RAS discussion on trailer light wiring

Back in 2002 I sent the kind folks at Cobra a note explaining that for
something like $30 in parts they could make any trailer headed for the
US plug and play.

Simply plug in an adapter to convert "euro" to the typical "flat four"
connector and flip a single switch at the back of the trailer. It only
would take 60 seconds at the port for the new owner to be driving away
and the lights would work. I suggested they just add $200 to each
trailer as "standard" and no one would ever bring up this subject again.

You can generally buy a what-ever-you-have-on-your-car to a what-ever-
you-have-on-your -trailer adapter at trailer stores. At least from
the car to a four-flat system.

A few suggestions if you rewire.

1) Go to a 4-flat system as that seems to be the most (least?) common
denominator, at least here in the US.
2) Go to LED lighting as they don't have nearly the corrosion issues
that incadescent lighting does.
3) Slather Dow Corning #4 dielectric grease on external connectors and
light bulb sockets to prevent corrosion and keep out water.
4) Use crimp connections instead of wire nuts or solder.

My $0.02.

Good luck, John

The glider isn't always plug-and-play, so we shouldn't expect the
trailer to be either!
Starting with a tow vehicle that has tail lighting of the modern
international standard, not the 1950s 4-wire system illegal in most of
the world, makes the job easier. US auto manufacturers only stay with
the ancient way because it involves less wire. Intentionally having
only one working brake light while turning is a strange concept.
Then decide which "large connector" you'd like on both. The US 7-pin
is quite common, but ones installed at the dealer seem to get wired as
a 4-wire system and most are plastic. I use the 6-pin round "redondo
de 6 polos", which has a metal chassis but unfortunately comes without
the 6 chickens.
With the extra pin(s) you can hook up reversing lights or interior
lights.
Build adapters to and from everything you can imagine, then perhaps
add adapters to bare ends, spade connectors or alligator clips, and a
roll of electrical tape to your kit. Keep the appropriate set in the
tow vehicle and the other set in the trailer.
If you make the adapter from your vehicle to European round,
electrically it'll be plug and play at the docks.
As mentioned before, LED lights are the way to go. Couldn't find
them in the US due to the abundance of stone age trailer lighting. The
most convenient place I found red/amber LED lights was ebay in
Australia. The same LED lights are available at many parts suppliers
there, but they may not ship overseas. The square ones I have are a
couple of mm smaller than the round hole in a Cobra trailer, so some
home made parts are needed to cover the edge of the holes up. An
example of the lights and cost:

Of course you can find "buy now" ones too.

It's "POLOS", nor "POLLOS" ... viva la diferencia!

PLEASE, PLEASE, PLEASE..........
TELL US IT WAS REAL plug and play....................
It would be nice to learn it functioned properly....
after all this is the year 2008 ano domini
man was on moon, long ago.

else;
try plug and pray, before touching anything

there are diagrams showing how to convert the European wiring to suite US
vehicles on my website "useful info page" and on my links to cobra trailers.
(From memory.....double check this)
actually converting the wiring is quite simple....the US 4 pin (flat plug)
wires are White, Brown Yellow and Green, the European trailer plug has all
these colors plus extra's for the separate amber and red lights.....connect
all of these 4 colors to the US connector, add the black wire from the
trailer to the brown wire, disregard the rest.....remove the tail light
lenses and disconnect the top bulb wire and connect it to the bottom bulb
(dual function bulb) leaving the top bulb disconnected and the original wire
from the bottom stop/turn bulb disconnected and you should have running
lights,side markers lights and stop and turn signal lights from the lower
bulbs.
again....double check this but I think this is going to work on almost any
European trailer with these separate amber and red tail lights..
also....even if you have a US vehicle that has separate amber and red tail
lights (most newer ones do today) the trailer wiring is set up for 99.999%
of the trailers in the USA that have only combination stop/turn signals!
And though some might want to put European trailer connectors on their tow
vehicles this is a really bad idea and something that we tried back in the
1970's to discourage since sometime you may need to have someone pull your
trailer to come get you out of a field and unless we all use a standard 4
pin plug there is little chance that you and you pal have the same connector
set ups.

Picking up a new Cobra trailer at the port on Tuesday......wondering if I
can expect just to plug it into my SUV motorhome and have the lights
working correctly? Anyone with a success story ?

Trailer and SUV are both fitted witht the new large plug and receptacle.

Thanks!
