If there is one thing that stresses me out is wiring of trailer lights, I had a few bad days managed to drive off with plug in on both my work trailer and my boat, now this would not seem like a big issue but they all came out so had no idea where they went.

A few weeks went by and a couple of attemps both failures, only attempted in good frame of mind (not an everyday thing :) ).

Wife only knows to well about me and trailer lights so when i go to do them she leaves, some of the neighbours may next time as well GRRRRRRRRR.

A couple more weeks go by and the rubbish is building in the trailer and the storms in November did not help. The wife suggests get a diagram of the net so I did a couple of versions in fact. So figure this is the go so with a bit of enthusiasm out I go a few hours later still not working and neighbours have opted to evacuate (PUSSIES GRRRRRRRR).

Calm down after a few beers (read lots) wife says get someone to come and do it, WHAT admit defeat HELL NO male pride is at stake now and 6 bleep y as$ wires are not going to get me. I few days later in right frame of mind figure I will go out and follow the diagrams again a couple of hours later son comes out and offers to help but takes flight, not sure if it was the glazing of the eyes, ranting of a crazed person or the flight of a few screwdrivers no matter what he was gone.

I sit on the draw bar for what seemed ages and just stared at the wires, diagrams, wires, diargams (you get the idea) finally I got up strolled inside wife and son get in car go out. FUC% male pride its overrated I get on internet get local auto electrician to come around he says be there this afternoon.

He arrives pleasent young fella I explain what I have done he says you think I should check how I had wired them up, go for it, kinda proud I had at least followed the directions (not a male thing usually do ) I figure there must be a break in the wires and say as much and show him the diagrams I used, just as he looks at what I have done, he says wires are all wrong and those diagrams are wrong, waste of thime using them ( I'm now thinking he better choose the next few works carefully).

During his VERY VERY short stay it now bucketing down with an afternoon storm hes under his rear door over the trailer hitch on the road and a few minutes later its all fixed $40.00 and hes on his way, wife looks at me and I say NOT ONE GOD DAMN word.

Wife could not help herself ...... Do you think he should do the boat trailer.

I have now realised if I break down out bush and its electrical I'm going to die.

Screw trailer wiring

Standard trailer wiring 101 .for 7 pin , Does not vary Aus wide.
Pin 1=yellow =l/h turn
Pin 2=black = rev sig
Pin 3=white = earth return
Pin 4=green =r/h turn
Pin 5=blue = service brakes
Pin 6 =red = brake lights
PIn 7 =brown = rear+clearance lights.

Every Narva blister pack of trailer plugs be it male or female ,
5 pin /6 pin +7pin that I have ever seen has the pin = colour = function printed on the pack.

When ever you buy a plug....shove the printed part of the packet in the glove box !!!!

Or write down the above on a piece of paper and do the same !!!!

Really is very simple if you have the numbers and colours !!!!

That's all very well if the trailer was wired up to the standard colour code.

Hi Brian, buy a multimeter and learn how to use it's basic functions. That way when you die from stranding with an electrical problem you'll know you've done your best :)))

I agree, but I still prefer a test light for checking trailer sockets etc.
I guess old habits die hard!

Electrical people , particularly engineers are much under-appreciated in our society and should be given regular cuddles, shown the best camping spots and they are always underpaid - and while we are at it - extra Exploroz discounts.

The above is the very reason I put both of my sons into electrical apprenticeships.

They both handle electical, data and coms. Nothing they can't do in those fields.

Then the mongrels up and left home - I'm back where I started.

Hi Brian
Here is a good site, with the wiring for most plugs.
Trailer Plug Wiring
It may help.

Jeez just reminded myself, the new GU has a different plug to that on my van so I may need your advise when I rewire the back of the GU this weekend before our big cruise down south for xmas break next monday. You may get the last laugh yet.

Cheers, Trevor.

I live in a retirement village and we have three trailers for common use and about fifty caravans privately owned. I made some test equipment up for testing the electrical systems. It composes a trailer (male) plug and a series of lamps, switches and a battery. All I need to do now is plug the trailer caravan in to test the lights. There is also a gismo to test the vehicle lights. Both are easy to operate but the biggest fault that I find is bad returns. I do not use the term "earth" as I believe that that word is inappropriate. The equipment saves a lot of arguments when the lights on the trailers work and the fault is in the vehicle. The equipment also has provision for electric brakes

Thank you to all the advise, I have a multimeter and a pointy gizmo with a light at the end (my technical speak), only have them in case I break down I'm hope the person that comes along can use them LOL.

Now I can handle (just) the $2000.00 in down time to cater to my male pride I can even the embarrassment of paying $40.00 to this young whipper snapper (his number is in my mobile now).

Now I seek your advise as you are more worldly crew than I. How do I stop the wife from giving me shi$ about my little battle with the those 6 bleep y as$ wires. I'm guessing from pass experiences with my wives memory I'm seriously screwed and this will be etched in her frontal lobe and I will be reminded till I go to my grave or I go and travel.

HMMMMM where are my maps.

Ask her to program the video recorder so you can watch Top Gear when you want to.

If the van is wired correctly and only utilises a 7 pin plug ,the blue wire.

Incorrect. The standard aux wire in a 7 pin plug is black, pin 2. This pin WAS designated for reverse lights but they are no longer legally required on most domestic trailers (including caravans).

On the van side, it is common to see the black changed to red or pink.

Blue is designated for elec brakes, pin 5.

Once somewhere in outback Qld, I disconnected the camper trailer, then moved the car without unplugging the lights, much swearing ands stuffing around later I rewired them. I now carry a laminated copy of this in the car's bookshelf. Image Could Not Be Found
