ground straps

I have a 1978 F100, 302. The motor has been replaced. Where should I have ground straps?

Thanks,

What I have and would suggest (though may not be 100% original) is at least 3. 1) Heavy ground wire from battery negative to engine block. This one handles starting and engine component ground when running 2) Moderate (eg. 10 gauge) ground wire from battery negative to body. I used the radiator support. This one helps make sure lights are well grounded. 3) Added ground from engine to frame in front. The frame rails have some pre-made holes that can be cleaned up and tapped for 5/16" or 3/8" bolt near the main engine ground. I added this one when I added electric trailer brakes to make sure there was good ground to the frame where the brakes are grounded in the rear.
