Indicators .... Can you help please?

Firstly hi to everyone tis my 1st visit here and also very very recently a new Husaberg FE 450 (08) rider.
Been looking at installing some indicators and mirrors to my newly purchased bike to make it more road safe being also somewhat of a novice rider too
My bike as the switch for indicators fitted up on the left cluster , also the green lamp on dashboard showing indicators on (if already fitted).
traced some wiring half way down the bike towards rear end/back light/brake light and half way along theres a 3 pin white terminal block.
This is all i have been able to find and or locate.

Could anyone with far superior knowledge and know how please give me an idea if its possible to just simply do the job as is ?
Any other wiring there that should be and i havent found?
Any help at all would be very grateful
Cheers
Phil

ps... there is a full set of indicators from an 08 ktm 300 exc on ebay but unsure if thats all i need and simply locate and plug in

Photo's and wiring diagrams very helpful.. thanks to you both
Managed to look a bit further at my wiring and it appears to be all intact minus the actual indicators and their end wires, so i have bought the ktm o8 set from ebay and awaiting its arrival.
So fingers crossed should be an easy set up.
Thanks again for your responses

Cheers
Phil
