TD 200 series LC trailer wiring

Just to add
The LC was wired by Auto elec' it has the loom already installed, problem we are 200ks from him and are trying to find problem without the drive back

I presume that when you refer to "can not get power" you mean the constant 12v for trickle charge to the van.

Now, I may well be wrong on this, but I don't think that the standard LC loom includes the continuous power circuit, only blinkers, stoplights, etc.

My 100 Series has a LC loom, but the constant power had to be installed separately by the auto electrician and the inline fuse is located near the car battery, not part of the normal fuse set up.

But maybe things are different with the 200 Series?

One other thought, you said you cannot get power for anything...

If that includes blinkers, etc then possibly the earth has simply come loose which would prevent all circuits from operating. I always get the auto electrician to run an additional earth, in addition to any in the loom, from plug to rear chassis of vehicle. The earth is so criticial, no downside in having an extra.

This is what the auto dealer did, in consultation with local dealer. also with limited information from toyota as they themselves know very little, The auto electrician will come to our place but can not predict everything to bring and having country experience it's always better to take it in.
We still feel it's something very simple like a fuse somewhere that we or they have missed

Maybe the "smart" circuitry requires a load connected before it powers up. This means the trailer socket is dead until the trailer plug is inserted.

Our Jeep Commander has a setup similar to that dicribed by Nomads UsR

Hi Everyone,

Standard Aussie wiring is Pin 1 Left Blinker, 2 Aux power (a separate heavy gauge wire with a fuse at the Aux vehicle battery) - utilux spec this pin as reversing lights..... Pin 3 Earth/Chassis.... Pin 4 Right Blinker.... Pin 5 Electric Brakes... Pin 6 Stop Lights....Pin 7 Tail/clearance lights.

I also ran a 6mm diam cable from BT A Frame to the vehicle tow bar (connect and disconnect at the vehicle) to provide a better earth return for all the 12volt services on the BT.

Hope this may be of some help in tracking down where power is/or should be.

Regards

Thanks everyone
