Steering wheel and centre console illumination not working

Hi guys... I've a 2008 Ve SS-V Ute, New member here hoping for some help. After poking around behind the head unit (stereo) on drivers side looking for possible blown fuse as my reverse camera and GPS weren't working, I in the end went over my cabin fuse box (should've done this first) and came across blown fuse on the cigarette lighter, changed fuse and reverse camera works and GPS... Problem is now that in probing around in all the wires I've upset something and now the illumination lights on centre console and steering wheel don't work... All the functions work just don't light up now... Hoping someone can point me in the right direction . Oh and in the cabin fuse box the steering wheel illumination fuse has no power to it... Fuse is fine just isn't receiving any voltage
