Hi, I have the same problem with the console lights. You refered to some other posts. Do they show how to do this?You need to send 7v down the iso pin with the grey and black wire, that connected into the back of the original screen (at the top).
You can take 12v from the cigarette lighter circuit (which is connected to the main lights) and step it down to 7v.
There's a few posts about it on here.
