Thanks for reaching out, Todd!

There are a few electrical components you'll need to complete the flat tow setup on your 2016 Chevrolet Colorado, so I'll list those below for you:

Roadmaster Diode Kit # RM-15267
Roadmaster Stop Light Switch Kit # RM-751472
Roadmaster Battery Charge Line Kit # RM-156-25
Roadmaster Battery Disconnect # RM-766 (For gas models only)
Roadmaster Battery Disconnect # RM93MR (For diesel models only, you will need one for each battery)

One thing to note is that if you're looking for replacement parts for your Brake Buddy 3, we unfortunately no longer carry Brake Buddy products, so I wouldn't be able to help source those components.

Are you setting the Colorado up as a replacement toad, or are you adding it to the lineup so you can choose between different vehicles depending on the trip?
