I have received my new stereo (JVC KD-R521) and installed it however it does not turn on or off with the ignition. I know this is because the standard HU was switched by CANBUS and that i should connect up to the ciggy lighter (12v).

I have swapped the red & yellow wires until the unit worked. The question is on the wiring harness (CT20VX03 Wiring Harness & Aerial Adapter) there are two loose cables. I presume one of these should be connected to the ciggy lighter?

Also do i need a male aerial connector?

Thanks in advance for your help!
