To install a brake controller like the Voyager part # 39510 that you referenced in a 1999 Chevy Silverado all you would need is the correct wiring harness. That would be the part # 3025-P. This will plug into the harness of the # 39510 and then plug into the port under the dash of your truck.

For more info on this check out the FAQ article I attached to the right.

The wire codes you listed are the standard wire colors for Chevy vehicles so if you need to wire a controller to them and not use the harness you would need to wire the:

Red of the truck to the black of the brake controller
Light blue of the truck to the red of the brake controller
Black of the truck to the white of the brake controller
Dark blue of the truck to the blue of the brake controller
Brown wire isn't used.
