They can been arses on the veccy c sometimes alot differs from model to model.on some theres a fuse at front glove box but sometimes there is no feed to it.
If no feed at fuse box then go to the passenger rear panel and tap into that for a switchable live feed in that.
If you have a model with parking sensors then it will need to be reprogramed not to turn them on when reversing with trailer is attached.
Good luck.

Is it a factory fit? If not being a witter then I doubt it

from the trailer module bit in the boot, yes... but theres no actual power to it

im told they need switched on with opcom though, sound true?

Have you run a +12v to the relay from the battery?

fitted my witter tow bar to the vec c, wire for wire by the instructions say...
seems to be no power to anything via the multimeter... had the trailer on and theres nothing ether...
am i missing something?
wheres the fuse?
some sort of switch?

any help is much appreciated :thumbs:
