Can't set custom controls to Custom Pawn

Completely new, thanks in advanced for all advice!

Trying to create custom controls for my player_pawn in a blank world. can’t figure out how to connect my controls to the actual pawn.

Game world is set to my custom one. Default pawn is set to my custom player_pawn. Default controller class is set to my BP_playercontroler. bp_controller is set to my custom IMC_PlayerController. I know i just need to connect this controller blueprint to the spawn pawn but am lost on how to do that.
