Question:

I have the tekonsha voyager brake controller. I took it out of the truck I had and need to put it in the 05 Suburban I have, the suburban comes already wired with a plug like end under the dash. Its the 7 wire trailr towing harness. Yellow, green, brown, white light green, red and dark blue. as you know the controller comes with Black blue, white and red. OK i get the 3 what about black? Plus can just slide them into the designated hole in the plug?

I have great news for you. There is a simple plug in adapter that you can use that will fit the Voyager brake controller on one end and a port on the vehicle on the other end. It is # 3015-P. I have included a link to a video showing a typical installation on a similar vehicle.

The brake controller wiring functions are:

White = Ground
Red = Input from brake switch
Blue = output to trailer to brakes
Black = 12 volt power

But since you have a simple plug in option, you will not have to hardwire the controller to the vehicle.
