I would appreciate help with the function of each of the colour coded wires which go into the Puma orange trailer connector. As mentioned in previous posts, this is located in the rear drivers side wheel arch (near the fuel filler).
From what I can see: Green/brown Left indicator Green/purple Right indicator Green/white Brake stop light Red/black Rear lights The ones I am struggling with are Black Earth? Purple ? Yellow/red ? Red/orange ? Green/red ? |

I think there is a pre wired plug in the rear drivers side wheel arch. Its behind the rubber flap. The pre wired cable (in the uk anyway) is relatively cheap.
Hope this helps a little. Pete. |

I do not know if this overview may be of help!
http://www.team.net/sol/tech/LucasColours.html Wiring Colour Code Table Many British designed vehicles use colour coded cables to assist in identifying the various circuits in use. This is an extract from BS-AU7a 1983 Colour Code for Vehicle Wiring, from the British Standards Institution, 2 Park St., London W1A 2BS. (Note that these colour codes may not apply directly to older cars. For example, the wipers on cars up to 1980 (at least) are not on a separate fuse circuit, so they are not orange, but green. Check the schematic for your car to be certain. - cak) MAIN TRACER PURPOSE Black All earth connections Black Brown Tachometer generator to tachometer Black Blue Tachometer generator to tachometer Black Red Electric or electronic speedometer to sensor Black Purple Tempreature switch to warning light Black Green Relay to radiator fan motor Black Light green Vacuum brake switch or brake differential pressure valve to warning light and/or buzzer Black White Brake fluid level warning light to switch and handbrake swith, or radio to speakers Black yellow Electric speedometer Black Orange Radiator fan motor to thermal switch MAIN TRACER PURPOSE Blue Lighting switch (head) to dip switch Blue Brown Headlamp relay to headlamp fuse Blue Red Dip switch to headlamp dip beam fuse Fuse to right-hand dip headlamp Blue Light green Headlamp wiper motor to headlamp wash pump motor Blue White a) Dip switch to headlamp main beam fuse b)Headlamp flasher to main beam fuse c)Dip switch main beam warning light d)Dip switch to long-range driving light switch Blue Yellow Long-range driving light switch to lamp Blue Black Fuse to right-hand main headlamp Blue Pink Fuse to left-hand dip headlamp Blue Slate Headlamp main beam fuse to left-hand headlamp or inboard headlamps when independently fused Blue Orange Fushe to right-hand dip headlamp MAIN TRACER PURPOSE Brown Main battery lead Brow Blue Control box (compensated voltage control only) to ignition switch and lighting switch (feed) Brown Red Compression ignition starting aid to switch Main battery feed to double pole ignition switch Brown Purple Alternator regulator feed Brown Green Dynamo 'F' to controlboxl 'F' Alternator field 'F' to control box 'F' Brown White Ammeter to control box Ammeter to main alternator terminal Brown Yellow Alternator to 'no charge' warning light Brown Black Alternator battery sensing lead Brown Slate Starter relay contact to starter solenoid Brown Orange Fuel shut-off (diesel stop) MAIN TRACER PURPOSE Green Accessories fuesed via ignition switch Green Brown Switch to reverse lamp Gree Blue Water temperature gauge to temperature unit Green Red Direction indicator switch to left-hand flasher lamps Green Purple Stop lamp switch to stop lamps, or stop lamp switch to lamp failure unit Green Light green Hazard flasher unit to hazard pilot lamp or lamp failure unit to stop lamp bulbs Green White Direction indicator switch to right hand flasher lamps Green Yellow Heater motor to switch single speed (or to 'slow' on tow- or three-speed motor) Green Black Fuel gauge to fuel tank unit or changeover switch or voltage stabilizer to tank units Green Pink Fuse to flasher unit Green Slate a) Heater motor to switch ('fast' on two- or three-speed motor) b)Coolant level unit to warning light Green Orange Low fuel level switch to warning light MAIN TRACER PURPOSE Light green Instrument voltage stabilizer to instruments Light green Brown Flasher switch to flasher unit Light green Blue a)Flasher switch to left-hand flasher warning light b)Coolant level sensor to control unit c)Test switch to coolan level control unit Light green Red Fuel tank changeover switch to right-hand tank unit or entry and exit door closed switch to door actuator Light green Purple Flasher unit to flasher warning light Light green Green Start inhibitor relay to change speed switch;

A few carry reproduction wiring harnesses. But very few carry the properly color-coded wire, and most of those only carry a small selection of colors and sizes. |

You can't use any of the UK trailer plugs in Australia. The only way to wire up a trailer plug here is by splicing into each wire individually (my auto-electrician left the original connector in place). Hence the importance of knowing which wire operates which light. 2007 Defender 110

Could you not cut the uk plug off the end? Then wire up your type of plug you need? Or do you need more than the functions we have?
Still doesnt help with the wiring colours though lol. |

Many thanks for the replies and help.
The reason I was seeking the colour codes is that I want to replace the original trailer connector. I have not been able to match that connector in Australia. And while a genuine trailer kit is available from Land Rover for some A$300 it will not match our Australian trailer sockets as our coding system is different, and will have to be modified anyway. Rather than cut into wires I will replace the connector all together and make up my own cable and Australian plug. The wiring colour code table posted by bjartin has been most handy as it confirms the main colour codes. Interestingly, Land Rover don't seem to be useing the tracer codes from that table. From testing the wires into the original trailer connector I am happy with direction, brake and lamp wires and can proceed. I wanted to connect up for electric trailer brakes and the Purple main wire seems to be part of that. I note that wiring diagrams are being discussed on in another topic area and will try to obtain one. In the meantime I left my parking lights on for a few days after tracing the wires and now have a dead flat battery. On a happier note it is raining here and my Puma has got wet. That's twice now since I got it seven months ago. |
