6th gen Radio Keyless entry/ Dome light problem

[DTvn]

I know you guys have probably answered this question before but I really need some help

I installed a new radio in and I knew I wouldn't get keyless entry but I didn't know about the dome light. I've heard of people somehow connecting the OEM radio with the new radio in and tucking it inside but i'm completely lost on that

Which connections go where, what harness do I need

Still need help

Got the hard part out of the way. Sorry for crappy pics

Still don't know where or how to connect the OEM radio though

Pics of the wires and crap

The black plug in the 2nd and 3rd pic go into my new radio but i'm not sure what to do with the 2 green ones.
