Where is ILL signal?

[segabor]

Hello,

I'm Gabor from Budapest, Hungary and this is my first post here.

I'm currently replacing the old radio to a new chinese android based head unit. So far it works fine, I managed to connect the original harness to the unit via ISO adapter. The only thing I miss is the ILL (illumination) signal. No idea which pin to connect. Without it buttons on the display remain dark and the display itself is not dimmed.
Thanks for the suggestions!

Hello and welcome to the forum

Afaik the illumination ‘signal’ is just a 12V (usually orange or white wire) that is active when the lights are turned on

I’ve recently replaced my stock radio in an 2011 built IMIEV (literally plug and play) and sure enough it dims the display when the lights are on.

You can easily check the functionality with a multimeter, if you measure 12V on ISO adapter pin A6 after you turn on the lights, the HW side is working, best to check the settings of the head unit then…
