radio/cig lighter fuse in AU1

[paddle]

Could someone please point me in the direction of the fuse for the stereo/cig lighter in my AU1? I brought my new/second hand pioneer stereo today,as all wires have been chopped by the previous owner in the car im sure something has touched and blown it out,have tested with a multi meter and get nothing,so I checked the fusebox but nothing has labels and I don't have a manual for the car,I would prefer not to have to rip all fuses out as I may reset something!.I am using the aerpro harness x 2,plugged the original into it but the loom still has an extra orange wire hanging off it,what is it to?
thanks
