Hi everyone, My name is Steve, I am new to the group. I have a 2013 GMC 3500 crew cab Denali. I live in Columbus,Ohio. I am a professional firefighter/paramedic/911 operator. My hobbies are Camping (in my RV), Motorcycling,Fishing, and Shooting. I love my new to me truck. I have a question for the group. I have a Bullydog GT I took off my 04 Duramax and I have updated it but I'm not sure which fuse to use to hook it to a switched ignition power source. Do any of you know which fuse to use? Any opinions about the Bullydog on a 2013 truck?
