Hi there,

Are there any standards for colour coding of the wiring for vehicle lights/indicators/etc.?

I'm about to fit front and rear bars and so will be re-wiring all the lighting in the bars to the lighting in the (second hand) bars. Anything that would make finding the correct sources and/or maintaining a system that an autoelectrician doesn't need to trace back would be nice.

I do have a trailer plug at the rear, so can draw everything I need for the rear from there.

Ciao for now
Andrew.

I'm not an auto elec so i don't know the answer. However i do electrical work on appliances and I NEVER assume that the colour of a wire means anything. You never know what someone else may have done to the wiring in the past.

Andrew,

There is a colour code, Nissan has one Toyota has one Mitsubishi one, and they are all different. The best way is to use a test lamp and check the wire before connecting.

Just for the record I don't work blind, and do use a test light always.

Thanks for your answers though - does anyone know the Toyota standards?

Ciao for now
Andrew who's off to google it.

Andrew,

green = tail lights
green / yellow = right turn
green / black = left turn
green / white = stop
white / black = earth
It has been a while (5 years) since I had to remember the code, but I am pretty sure that this right.

If coming out of a 7 pin trailer plug the standard is..........
1. Left turn yellow
2. Reverse black
3. Earth white
4. Right turn green
5. Brakes blue
6. Stop red
7. Tail lights brown

By using the standard trailer wiring colors you'll be able to source the cable easily instead of trying to match the striped multi colors used by your particular car & then auto elecs should have no trouble understanding it.

Number 2 can be auxillary positive from the battery.
On a 7 pin plug that is

Crackles data is correct - it corresponds with the relevent Recommendations (AS 2513 and AS 4177-5).

But do note that many caravan makers use Pin 2 (in 7-pin connectors) for auxilary lighting. This seems to contradict the ADRS - but I have never been able to get a straight answer out of any 'van maker re this.

Also in caravan wiring generally, Red is commonly used for active and Black for negative. But Jayco (and a few others) for reasons that seem to defy logic use Black for positive and White for negative.
Trust this helps
