Trailer wiring loom

G'day all.

Just reinvigorating this thread.

We have recently bought a 2011 Prado and we're having trouble getting the trailer lights to work. I've checked all the fuses (box under the steering wheel requires a contortionist to access and use). All good. I read somewhere (probably here) that the number plate light can go off if there's a loose wire in the tailgate. Could this be related to the trailer not working.

We have a round pin connector and the trailer lights work fine on the other trailer (round to flat adaptor).

Hubby has just taken a preliminary look at the plug connections and all seems good there. But as he says "He's a boilermaker not an auto sparky". LOL

Hope to hear from someone soon.

Does the trailer work on another vehicle? If one trailer works and the other doesnt it points to the trailer. Maybe bad earth but easiest check is hook it up to another car and test. Another possibility is tgat your Prado and the trailer that works are both wired the same way incorrectly but that would be rare. Either trailer use led lights?

Assuming the trailer lights dont work on another vehicle you can download the trailer plug connections to check. If the plug is ok then check at the lights. If they are ok then there is a cable problem.

Boilermakes can do wiring too!

Hi,

Yesterday i replaced the trailer plug on my 2003 120 series prado and everything went fine, afterwards i was driving around and my blinkers stopped working, the bulbs and dash lights are not flashing. When i use the hazards everything works fine. Any ideas

Does it come back if you unplug the towing relay?
