How Many Wires Under Hood of 2003 Chevy Silverado Need to be Connected to Install Brake Controller

Question:

Hi, I watched your video where you connect the 2 red wires on the fuse box and also connect the 2 blue wires. There appears to be only one red wire and one blue wire. Your video shows the missing ones coming up close to the firewall and dont look like they are coming from a local harness. Where are these wires? Did GM forget to put these in some vehicles? Thanks,

There should only be a single red wire and a single blue wire needed to connect under the hood of your 2003 Chevy Silverado. If you check out the help article I attached you'll see that the blue wire has a plug on it and the red wire has a ring terminal like what you sent in a picture of.

I am not sure what video you are referring to but what you have in your hand is totally normal and would be all you'd need to connect.
