Hi, I am having troubles with the wiring on a 6x4 trailer.I pulled everything off to use trailer as an extra feeder for some weaner cattle.Before doing so I wrote down where each coloured wire fitted but when I replaced them they would not work as before.The brake light and park light flash on the left side when I put the left indicator on instead of the bottom single element globe. I hope someone wiith wiring knowlegde can help me out as I do not know enough about auto electrics.
The wiring on the trailer is as follows.
Left side Top Globe Right side top Globe
0 Red O Brown O Red O Brown
Bottom indicator Globe Bottom Indicator Globe
O Yellow O Green
Then White to earth Then another white earth
Also 2 yellows and a white Spare
which were twisted together to
make 1 connection.
If anybody has any suggestions I would be grateful as I am in a remote area at present. Cheers

Hi there Drifters,
Here is the wiring code for all trailers and caravans/
Trailer Plug Wiring Code
1 Left Turn Signal Yellow
2 Reverse Lights Black
3 Earth Return White
4 Right Turn Signal Green
5 Electric Brake Wire Blue
6 Stop Lights Red
7 Tail Lights Brown
Determine what wire is what by using a small
test light or a multi tester
then wire into the plug accordingly.
These numbers are the same whether the plug or socket. Plugs and sockets are numbered correspondingly.
Cheers, Bruce.

Please ignore the colour coding on my list as yours seems to be different altogether. Once you have worked out what each wire does then wire it into the plug according to the nubered location I have listed above.
Cheers, Bruce.

A cheats way to remember the colours for a basic trailer:
Red is the universal colour that means stop.
Left is the yeLLow wire.
Right is the gReen wire.
Earth return (ground, if you like) is the opposite colour to 240v house wiring, therefore is White.
Leaving Brown for parking/clearance lights.
I use 7 pin flat connectors which have the functions of the pins printed on the case, so I don't have to remember what pin does what job. Yes, I am a cheat.

Hi Bruce, Thanks for that. The wiring code you discribed is the same as
mine. I cannot get the yellow wire on the left turn signal to work. There are 2 yellow wires on the right side that are not connected but when I join them up still no action so it looks like I will have to
check the wiring harness from the front connection to the lights at the back. The right blinker works OK it's just the left that's testing me a bit.Thanks again for your reply. Much appreciated. Cheers Bruce

Hi folks,
I presume you've tested all your globes, too? (i.e. continuity
test with a multi-meter across the terminals. You can pick a cheapie up from abot $10)
If you're running those silly festoon globes, the globes can sometimes be fine (although my history with them suggests they're at their best at the bottom of the rubbish bin), but a lack of tension on the "holders" - and I use the term loosely - won't give you a good enough contact to complete the electrical circuit.
Not arguing about others' comments, but even if the plug's wired properly for a 5-pin set-up, it won't work with a 7 pin socket either.
Good luck with working it all out. :-)
Regards,
Charlie

Hi Charlie.I Will take in what you suggested and
check with the multimeter for any possible faults in that direction. Thanks for your reply. Cheers, Bill
