We tow a 2004 Saturn Ion and have had no problems until this last weekend. The Saturn power outlet fuse would blow when the Brake-buddy was plugged in. We never had this happen before and we were thinking something is wrong with the Brake-Buddy.
I called Brake-Buddy and found out that the 2004 to current Saturn's used a wire size too small. The resulting wire resistance causes too much additional current which blows the fuse.
Brake-Buddy shipped me 12 volt installation kit at no cost which is wired directly to the battery. They provided cable, hardware, power outlet, an in-line fuse holder, and instructions. It was a 30 minute job to install.
If you are having similar problems with your Brake-Buddy call them...they will help.
