Fitting R&G tail tidy and indicators

Just fitted a new R&G tail tidy to my s1000rr 2012. Cut the plug off and wired the plate light into standard BMW plug. Surprisingly it worked. Now wanting to fit the BMW led indicators. They seem to be a standard fit but you have to buy the attachment plug for s1000rr for rear indicators. If I buy the said plug how does the plate light work into the new plug. I can buy the rear indicators off a scrapped s1000r 2014. I assume same indicators but is the plug the same

Just for for reference I own a hammer, spanner and a Phillips screwdriver, in essence im not electrically or mechanically inclined but can bluff I or cuff it

Update::

Gonna buy 2 sets of the OEM bmw led indicators new. Front and rear. Assuming the front should be plug and play I'm going to have a look at fitting the rears. If anyone has any experience in wiring in the rears all advice is greatly received.
