Well I'm no sparky (see above :) ) so I took the inside panel off to see if the connector was on wrong and found this.

Am I right that even though red goes to the middle pin and black to outside on the socket that the connector is arse about ?

If so which way is easier, rejoin the wires somewhere between the socket & connector or get an auto elec to fix the connector or redo the socket ?.

Is the Black on the right side of this plug in the picture on the right the earth and not the green and yellow stripe?

Mine is exactly the same. If i measure with a multimeter at the moment, with a filament globe in the socket. From the side of the globe to the chassis is a direct connection to earth. Meaning the centre would be +ve yeah? And that's how it should be right?

If i cut and swap them then the centre of the socket would become the -ve and the side of the socket the +ve. To me that would be wrong. As you say a filament globe would still work, but if all the other sockets on the car are wired the same why do they work and not this one?

What are you measuring voltage or resistance/continuity?

What is the voltage reading, brake lights on, positive of multimeter connected to the centre pin and the negative connected to the housing, is it a positive or negative reading?

Continuity from side of globe to chassis is 0.00 earth. And A normal globe works fine. But swap the globe for an LED and i get nothing. If the side globe socket is +ve and it is a direct connection to the chassis like people are saying they have to change to then, wouldn't the whole care become live??? And then short out?

My way of thinking you can't have one socket wired one way and another the opposite when they are powered in the same system or circuit.

The socket is above ground it mounts into a plastic light.

I think you will find you are getting continuity through the bulbs.

Measure the voltage across the socket and pay attention to the polarity of the readings.

I hadn't thought of that. I will check it out without the globe in and see what i get.

You will need to remove all brake light bulbs as they are connected in parallel.

Would be much easier to measure the voltage.

Yep got the wrong reading before. Took the globe out and measured the continuity from the centre of the socket to the body of the car and sure enough it's been hooked up opposite to the whole car. Thanks for that Yendor.

Now for the quick snip and rejoin.

Also for those in this position. This is if you have steady hands and a little patience you can actually swap the red and black wires in the plug itself. There fore no cutting or re-joining like i was going to do and everyone has probably done.

Upon looking at both plugs and a little poking with a little hook/pin tool i had, You can actually pick open a cover exposing the bare wire terminals and gently push them out, swap them over and push terminals back in until they clip back into the plug.

Then gently, in the reverse to opening the little cover, clip it back into place.

Now once you have put it back together, either globe will work no problems.

So looking at the last pic and holding the plug as I am, red on the left black on the right is what you should end up with if successful.http://www.nissanpatrol.com.au/forum...cons/icon7.png
