Technical Live Cable for Lights and permanent/switched lives

[typecastboy]

Just installed a 7 inch screen stereo from Ali Express into my Series 3 car. I've wired it into the BCM fusebox. Red cable to permanent live and yellow to switched live. I could have wired into the existing loom but for now it's fine. Just wondering if anyone had the pin outs on the plug that goes into the back of the factory stereo. I need to identify the permanent live and the switched live. Anyone help.

I also need to find a lighting live. It was suggested that I tapped into the light live on the heater panel, again, can anyone tell me which is the live for that which switches on the bulbs when you turn your lights on?

The easiest place for switched and lighting is the power socket/lighter beside the hand brake.
Even though our cars socket was not illuminated the lighting feed wire was there

Thats a good point actually. I've never really noticed, does the accessory socket light up when lights are on???

Mine does now (the original was not illuminated)as I replaced it with an actual lighted lighter socket plus a dual USB outlet beside it , yes it lights with the headlights

Bu you didn't need to do any further wiring. Can't say I've ever notice one way or the other. This is a Colour Therapy, so souped up Pop so probably not.

No the wiring is already there just the illumination wire is left un connected on our 09 pop
