Your 2010 Chevy Silverado 1500 can be connected to your Hopkins Agility Trailer Brake Controller, part # HM47294, as follows:
Vehicle red/black wire connects to the black wire on the controller (for 12V power to the controller).
Vehicle solid white wire connects to the solid white wire on controller (for ground).
Vehicle light blue/white wire connects to the red wire on the controller (for braking input signal).
Vehicle dark blue wire connects to the blue wire on the controller (for brake output signal to trailer).
The orange wire does not connect to the Agility controller.
You may also need to make two wiring connections within the engine compartment in order to make the tow package functional. One wire is the power wire to the brake controller and the other is the trailer battery charge line to the 7 way connector.
These wires are both Red/Black with eyelets on them. They are coiled up and need to connect to the under hood fuse box. One of the wires is located between the under hood fuse box and the left (driver) side fender. The other is located under the master cylinder/brake booster assembly. The battery charge wire and the power wire to the brake controller have different size eyelets on them and will connect to the threaded studs under the Gray handle at the front of the fuse box. The two studs are different sizes. GM does not supply the attaching nut required to secure the wires to the studs. These can be obtained locally. You will need (1) M6 x 1.0 nut and (1) M8 x 1.25 nut.
I have included a photo showing the location of the two wiring studs. I also linked an article that covers this entire process.
