I'm going to have to take it to an expert I think.

What about un-wiring the trailer socket first, it may look ok but stuffed inside.

The wiring at the plug is sealed requiring the sealant to be dug out to access the retaining screws.

Ok... thank you! Good advice which didn't quite sink in first time around.

I am not good with this stuff, bear with me, I can't seem to access these plugs without removing the rear bumper. The plugs are tucked low down under the light and behind the bumper. Is there a trick I'm missing here?


And also yes to the sealent in the plugs. I saw that and assumed would be all good. Again though, not sure how to access this without removing the wiring from the back of the plug. Can unscrew for the rear but only loosen the plug a bit but still awkward to access from either side.

Not a handyman or mechanic so grateful for your advice!

Read Graeme's post, #8.

Solved!
Previous owner had replaced a seatbelt and drilled it through the wiring. I didn't find it myself. Asked if they'd look at it for me when in for a service today. Something that would have taken me a lot of hours over many frustrating, divorce-inducing weekends.

Not sure exactly what the issue with the seatbelt is, haven't got the car back yet - that's a different story, and a little too painful for today.

For the record, I still never figured out how to unplug the trailer wiring from behind the rear lights - the wiring sits to low behind the bumper, and I couldn't get my hands in there without needing to take off the rear bumper.

The rear light cluster is held by 2 screws accessed with the tail-gate open and 2 press-stud type fittings on the outside. With the 2 screws removed, carefully but firmly pull the assembly straight back, working the top then the bottom out. Be careful not to twist the assembly outwards lest the prongs on the light assembly snap off, as they don't like to be bent and are not replaceable.

Thanks Graeme, and sorry I wasn't clear, I was able to remove the lights but the wiring was lower than the space behind the lights it was juuuust out of reach for my fat hands or pliers or something down low behind the bumper.
