need a little help on big 3 grounding

[jsluss17 10+ year member]

is this the factory ground for my battery? there's a lot of wires and i think this would be it but i can't tell and if it is it it's a pretty bad ground i think. the car is a 2003 mustang btw

also would this be a better ground? i think it's the strut tower not sure though

one more thing i'm confused on the engine block to chassis where on the engine block do i put it? i'm not very good at these kinds of things

Best place to ground is at your alternator bracket on the engine. Strut tower isn't the best place to ground at either.

so would the bolt on top of the alternator right here be the best place?

someone answer this. he did post pics. I'm also wondering if your alt casing is your ground so that goes to chassis? then from chassis to bat -

oh and when i say chassis i mean frame i think frame is better than chassis

theres more to it than just saying that the best ground is at the alt bracket...

so i run the wire from the bolt on the left of the alternator in the pic to the battery? and then what do i run for the engine to the frame? sorry i just want to make sure for sure i'm not good at this but i appreciate the help very much
