Ever since i installed my aftermarket headunit into my 2003 octy vrs its never come on and turned off with the ignition. There was no unit in when i bought the car, i have to use the units power button to turn on and turn it off. I think this is how the previous owner had theres installed. Ive changed some wires around and nothing changed after delving further down i discovered some wiring. Ive taken pictures.

Wires at back of unit

Blue block ive discovered, i think the main power wire is attached here

Then theres this wire not connected?

Can anyone help? I was going to connected that wire back up however the other end is attached in the blue block connector

you may need to switch the yellow and red wire around,  

Which ones? Ive switch the two around directly behind the headunit and it was still the same

Just get a multimeter and identify the permanent and switched live feeds on the wiring loom, then make sure they go to the correct ones on the HU loom.
