Hi All,

So I've been replacing the 7 pin dealer fitted trailer plug on my 2015 MUX with a 12 pin, ran some additional cables with some relay control etc. Wired most of it up a couple of weeks ago, added the 12V feed to pin 9 today and redid the connections that I did last week on pins 10 and 11 as it was a bit rough.

Now the reverse sensors have stopped working.

Reverse lights trigger as does the camera, I've disconnected the reverse signal in the car plug which was pin 2 as the caravan has a break-away sensor monitor pin wired to this (not required in VIC) which was upsetting things but I did that a couple of weeks ago and the sensors have been working fine.

Any suggestions of things I can check?


Cheers

Zarniwoop

By fitting a 12 pin you have removed the magnet in the lid of the OE plug which earthed the sensors and made them work when the lid is closed. Now no magnet and Reed switch doing the completion of circuit when lid closed.

Thanks , yes I discovered this just a short time ago by examining the old socket. Time for a new socket...

If you have 1 pin on the 12 pin base not used, you can simply insert a piece of heavy copper wire in there as a jumper which will then connect between that wire pin and the earth pin of the socket.
Alternatively, use a small toggle switch which connects the sensor wire to earth whenever you have the switch in the correct position. Switch open when towing.
