Connecter Help Needed

My '08 Scrambler is one of the last of the 865 carb models and has the slightly larger EFI tank. I suspect it also has a later loom as there are 3 unused plugs which earlier Scramblers don't seem to have. I've had a look at the wiring diagrams in the Haynes manual but struggling to spot them.....

So can anybody tell me if any of the plugs in the pics below (2 under the tank, 1 by the airbox)could be used to power accessories such as heated grips, and if so what type of male plug do I need to use?

TIA

 

Partially answered my own question by looking at a different diagram! The oblong connector with purple/black feed is 'the' accessory connection, would snip off the bulky block and connect direct to the wires.
But I'm still curious about the other two so any thoughts still welcome - and what is that type of plug called??
