If you are installing your own wiring for the Prodigy P3 # 90195 on your 2012 GMC Sierra 3500 like our Universal Wiring Kit # ETBC7 then you'll need a 20A Circuit Breaker # PK54220 for that application.
According to my research though you should just be splicing the controller into existing wiring found under the driver's side dash of your pickup. Aside from that you might need to make a few wiring connections under the hood near the fuse box but that wiring should already be ran for you as well.
