Help with trailer brake

[conoco]

Is anyone familiar with the set up of this trailer brake. Everything is hooked up accept for the two wires in the picture. It is hardlined into my proportional valve and the green wire is hooked up too. My truck is completely stock electrical wise other than the hitch and connectors. They guy I bought the truck from use to tow his race car and trailer. It very well could be hooked up already. I just dont know if the two wires that are disconnected need to be hooked up to anything. If so where do they hook up too. The plug in the rear of the truck works. Like I said it very well could be good to go. Just trying to see if the vast knowledge on this site could help me with confirmation. Thank you.
