V70 towbar wiring plug

[hussar]

Hi All
Just fitted a Witter detach tow bar, really supprised at how easy it was. The kit came with a bog standard 12n wiring kit that splices into the cars loom. It works fine but doesn't half look untidy. Ideally I would have plugged straight into the purpose made connectors that are ready and waiting.
My question is - can I get a plug in connector that I can wire my present cable into and then plug it in? If so does anybody know where I can get one?
Thanks in advance
