Towbars and wiring

[Top drive]

Good morning 

Looking for a towbar and wiring for my 2015 partner tepee outdoor

The towbar I'm pretty sorted with -a Witter flange mount -needs to take a flange fit bike rack I already own. 

But the wiring has me confused. - I think I want a plug in solution rather than a bypass job. 

I have lexia3 so can activate what ever.... But what I can't find is a part number and retailer for what I need . There appears to be a few options how do I figure out which is right for my car. 

More so that my car was registered in December 2015 and June 2015 appears to have been a model change over. 

Thanks
