Pictures should speak for themselves. I personally didn't like the idea of poking holes through main wiring grommet located near turbo. Crack open wheel well splash guard, and at very bottom you'll see a rubber slung. Remove slug. Open drivers side door and remove both trim pieces from the trunk/fuel door release and hood release. You'll see hole in picture where I shoved flashlight. Pull string from interior hole through wheel well hole. Then fish down between fender from above into wheel well and pull line back through. Secure wires away from hood pivot point and secure thoroughly under splash guard. I attempted to drill out rubber slug to fit multiple wires but it's too tight. Plumbers buddy or duct seal should do the trick to seal off wheel well hole.
