Useful Wire Colors and locations

[GeeWhizz]

Just about all battery negative wires (ie. chassis/ground) in the dashboard are black with white stripe. Black with white stripe is not used for anything else in the 150s, so you can't go wrong.

Hi guys,
I'm installing a Redarc dual battery voltmeter and in calls for positive polarity from the park lights, negative from the dash lights, ignition and ground. Ignition and ground I can get without too much drama, but I've been stumped on the other two (+VE park light, -VE dash light). Anyone have any idea where I can get a tap from under the dash? Would be much appreciated, I've been hunting this down for too long now! For clarity, I've got a 2010 Kakadu.
Cheers!

I would ring Redarc customer support. Considering the dash lights are normally +VE and ground, it doesn't make a lot of sense.

Don't worry, found a body earth stud just out of view in the jack compartment. Just follow the thick white wire.

Hi Maxjj,

The following seems to be the easiest pick up of IGN switched 12V at rear of car.

There is a White socket in the Jack compartment that will have the trailer wiring plugged into it.

In the picture below the trailer harness is on the right and the car side wiring is on the left.

There is a thin grey wire up one end opposite the yellow wire and next to the light green wire.

This grey wire is protected by the 7.5A IG1 fuse and is only at 12V when the ignition is on. (I didn't check if it is also on at accessories switch position.) It appears to be unused on my car as there is no wire to it in the mating socket to the trailer loom.

There are a heap of other circuits fed from this fuse so it would be advisable to only use it as a sense circuit and not draw power from it. I intend to tap into it and use a 1Amp fuse to protect upstream circuits.

There is also another grey wire on this socket. Thicker and having permanent 12Volts located in the centre of the socket. Likewise the heavy green wire is also permanent 12V. These wires are protected by 30 Amp fuses "Towing BRK" and "Towing". Not convinced that these wires are capable of anywhere near 30Amp though look way too thin.

Cheers
Prone

Hi,

Can anyone tell me which colour wire on there is ground or negative? I want to wire a relay to switch a red anderson for my caravan. I'd prefer to wire tap a ground/negative rather than putting screws through the metal work.

Thanks,

Hi, poes that little panel where the 3 pin plug is just pop out?

Use a plastic lever at the bottom of the module to pop it out of the corner panel. I bought a kit like this from Jaycar a few years ago. Great if you want to get behind many of the panels in any car without causing damage.

I haven't found one and decided the easiest way is to pull one out from the inside cabin. In my case I did install a 2nd battery and then a relay to provide IGN power to various consumers.

That is a brilliant idea!! Running 12V accessories from the 2nd battery with the IGN power set as the Relay trigger to consumers.

TO THE SHED!!!

Hi All,
The plug I referenced above (near right hand headlamp colours are, white, white/black, black, green and purple. Any ideas as to what the plug would be used for on other models ?

Hi Gee Whizz, I will look at the plug again on the weekend and note down the colours.

Can anyone confirm that the 2020 Prado does not have a radio security code ? Don’t want to disconnect the battery then find I needs code to get the radio to work

Hi All,
Have just purchased a 2020 GX Prado. Looking for 12 volt power IGN power in engine bay. There is an empty plug on the radiator support near the right hand head light. That’s 6 wires going to it. Can anyone tell me what this is used for on the different models.
Thanks

It's possibly related to the "Headlight Cleaner" (wiper control), although there are a LOT of connectors in the engine bay. Wire colours are Bk, Bk-Wh, Grn, Lt Blue, Wh, Vio? Give us some more clues.

Tapping into Green wire in the DAC 4 wire plug next to the Hi Low selector can be used for switch/dash illumination. Earth wire (if required) goes to the bolt behind the triangular padded panel in the passenger foot well.

cheers Geoff appreciate the info on the 5v, so does yours run all the time for like parking mode, thanks for the info

No, I have connected to the sunroof +ve. I have the G switch option that will start the camera via its battery if the vehicle is knocked. My camera goes to sleep 10 seconds after turning off the ignition. It's a Navman Mivue
