For Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - GM Item # 3015-S the black wire is 12 volt power into the controller. White is the ground. Blue is output to the trailer brakes. And red is input from the brake switch.

Take a look at the help article I have linked below that explains where and how to wire in a brake controller on your 2004 Chevy Tahoe (and other related vehicles).
