well, i did the BIG 3 grounding wire upgrade today and i noticed a big difference in my stereo not dimming, but the car runs like crap now. i did it exactly as described, but its not running right. the one thing that could be the problem is i did the block the chassis wire from the stock block grounding point, and the relay that i think is for the fan. my fan stays on the entire time my car runs now....could grounding it at the point the relay is attached to the chassis cause the car to bogg down and the fan to continuously run???

only one way to tell. undo it and run without it if it runs good ground it somewhere else?
