Need radio help.

Can you guys help me out. Got a factory radio and display off eBay. Hope it's not damaged. All I get is a boot screen and then a dim display. No buttons work. Factory wire harness just arrived.
I can't get my IPad set to let me post pics. I have a couple plugs I'm sure about.

There are two plugs on driver side close to the speaker plug. Anyone tell me what they go to. And would the radio need programmed

These

your right. You take the plug from under the steering colum and pull it back out to the ecm base. The radio harnes has one plug that plugs into that and it just clips on ecu base The other plug on radio harness is routed back under the steering colum for diagnostics. Now the radio is routed through the new diagnostics. And radio works!! Thanks for the help guys.
