Expert Reply:
From what I was able to find, the 2008 GMC Topkick 5500 does not have a port to plug in a brake controller wiring harness. A brake controller will have to be hardwired into the vehicle using a 4 and 7 Way Installation Kit, # ETBC7.
Usually, this would require the installation of a 4-Way wiring harness first that would then plug into the back of the ETBC7. However, there is not a 4-Way harness available for the Topkick, so you will need to clip off the 4-Way plug on the ETBC7 and hardwire the wires directly to the taillights.
Brown goes to the taillight circuit, green goes to right turn/brake light circuit, and yellow goes to the left turn/brake light circuit. The ETBC7 kit comes with 25 feet of wire but you may need more of # 10-2-1, and a circuit tester, # PTW2993, to find the correct wires on the vehicle.
After that, you can follow the installation details in the FAQ and video links I have provided for the ETBC7. For a brake controller, I recommend the Tekonsha P2, # 90885, because it is easy to set up and easy to use. I have included a link to the installation instructions for the brake controller as well.
