Useful Wire Colors and locations

Exactly right, it is used to power a relay mounted in the van. The relay switches the Van bat power to the fridge. It seems a lot of vannies run the 12V fridge power through the trailer plug (pin 2 which is the rev wire), to my way of thinking trailer plugs are not designed to run large current. It obviously works but to me it is high risk.

Anyone able to advise what the wire colours are for the reversing camera and what plug they come thet go to behind the player?
Thanks
Mike

ABR sidewinder has put up a thread on how to modify the reverse camera wires to add an on/off switch.

Just added a switch (newpro-tech) and relay to be able to switch the reversing camera on when I want it on. Picked up the dash illumination power from the plug for the mirror adjustment panel. It is the GREEN wire, second from RHS, between the white and purple wires.

thanks guys ... well done finding the 12 ACC wire under the bonnet

Anyone know of a pick up for IGN that is only on after the car starts? Preferably down the back of the car as I will be running it to a relay for a 3 way fridge.

I did go looking for the green wire near the 240V outlet as outlined in the post above, but it is not there in a GX.

Cheers.

only on AFTER car starts?? not sure that one exists! IGN ON means ignition on regardless of engine start. I take it you have seen the post above for 12v on IGN location?

Yeah I have thanks. I'll use that and send it through the reverse pin in the trailer wiring I think.

Thanks PradoPointers!

Just used this info to wire up my $7.49 LED Daytime Running Lights. Probably don't comply with ADRs but seem to do the job. Look a bit brighter in real life than in this image which doesn't quite do justice as seem lost against the white duco.



Cheers

"Green Wire, Drivers side of the Engine Bay above the brake booster going to the wiper motors"

How do I tap into this wire? Any suggested methods?

[footoo Member Find all posts View Profile Close footoo]

The easiest way. Skin it, wrap your new wire around it, solder then wrap with electrical tape. For added protection smear a bit of silicon/silasitic over it.

That's how I do it..

Actually, the easiest way is to buy a wire tap connector. Though, I also do as footoo has done when I don't have a wiretap connector handy.

IGN wire in rear of vehicle

Ok, so I have found an ignition wire (similar to the front wiper motor) in the rear. I found it from the rear wiper motor :-)

All the wires going through the flexible conduit into the rear door are black, however up near the motor, then pass through a connector and then regain their colours. I found that the purple wire was live with IGN on only, so i then used the wire tap (post above) and fed a wire back down through the flexible conduit into the car.

Im pretty sure you could trace this wire down to the rear quarter panel if you wanted to, but they are all black there, so identifying it may take two people (instead of running up to the front of the vehicle to turn on and off the ignition.

I then went on to wire this into the 'reverse' pin of the trailer wiring harness, and am using it to trigger a relay to run the 3-way fridge (on 6 b&s).

I have not checked this but be careful with the purple (violet) wire I believe this is the washer motor operating wire. Grounding this should cause the rear washer motor to operate. Putting a load on it like a relay may cause a constant current to flow in the washer motor leading to heating, the current may not be enough for it to operate though. Pulling the 15A fuse WSH RR in the engine fuse block should confirm this.

I think the wire you actually want at this connector is the Sky Blue wire which is the battery supply to the rear wiper motor.

Both the above circuits are protected by individual 15A fuses (WSH RR and WIP RR) supplied from the battery (via a 30 fuse WIP WSH RR) through a relay that only operates when IGN is active.

Fuses and relays are at left hand end area of engine fuse block looking from front of vehicle.

If I am wrong somebody will correct me I hope.

Good luck

Thanks Prone, I'll check it out and see what it does. Do you have a wiring diagram that you are referring to?

All the reading on the net I can find indicates that the relay should only draw around 30mA to operate. Surely that won't be enough to cause heating will it?

Also, the wiper motor will only run if it is grounded through the motor right? Having tapped the wire 'upstream' (ie live) of the wiper motor it shouldn't run should it?

Sorry I'm a bit of a basic 12v hack.
