I am getting ready to replace my engine wiring harness and battery cables. I noticed that the negative battery cable that I have has a ground wire attached to it that secures to the radiator wall frame.

However, when looking at the original battery cables, none of them seem to have a built-in ground wire on them.

1.) Is the built in ground wire necessary?
2.) Is the built in ground wire strongly suggested?
3.) Pros/cons of keeping it or going to original cables?

One attached pic is of the cable with built in ground wire. The other pic is an original set up without.

69 had cable that went to the head and was painted with engine so about half of it was engine color. Check ground cable from engine to body. Comes from rear of passenger head to frame.

Just to say in restoring this car will run a ground wire through out the car. Had problem's with another car year's ago and ran a ground wire to the tail light's solved my problem.
