I see this mistake time and again -- and it really just shows a lack of electrical knowledge...
There is NO REASON to run a GROUND cable "forward". Just run the ground cable to the nearest convenient point on the chassis or body. Then be sure to run a separate ground strap from the body/chassis to the engine block (the largest amp draw when cranking).
GOOD solid grounding is just as critical to the electrical system as the Positive side. Remember electric is a CIRCUIT...
If you ground thru paint - on your smaller connections... be sure to use a STAR WASHER UNDER the connection. These are designed to cut through the paint and dig into the metal. Don't use a split washer which was designed for a completely different use.
Running the positive through body cavities --- is just a fire waiting to happen... if you do this -- be double triple sure you've protected the cable from chafe (remember you can no longer see it and check it!)... and that you've put some kind of retention every 6". You'd be surprised how much vibration is in a car going down the road!
