Grounding Mod

I just finished installing a set of paranoid fabrications grounding wires which I got for Christmas. The car seems to run smoother, I'm quite pleased with the results so far. I will post up some pictures as soon as attachments are allowed again.

The problem: Weird clicking noise inside car upon start up. Go outside and see that the front blinkers and rear brake lights are lighting up and turning off over and over. It is NOT the hazard lights. This happens periodically (every other minute or so) even with the car off and the keys completely out of the vehichle. Anyone know what could be causing this? Maybe connecting to the negative battery terminal? Maybe I botched something? a fuse? :?
