Ground Strap vs. Ground Cable

Your engine (et al ) is (probably) going to grounded some how some where.
A bonding strap is a good idea.
Now whether the original engineer of your car meant that to be the primary return path or not, I have no idea. But I sort of doubt it.
Is this why you are still wondering?

Yes, but no. I am grounding my engine from the head to the firewall. That thread is what got me thinking about whether I should switch to a strap. Now granted Im not a electrical guru like some of you on this site, but to me as long as it has a path to ground and a good path you shouldnt have any issues at all. Im curious as to the reason they used straps, and what everyone is using in there car.
