Best place for negative battery ground

[Kmart75]

I just got new cables made and wonder where you guys are connecting the negative battery cable. When I bought the truck it was connected to the alternator bracket, is that the factory location? Is there a better, maybe cleaner looking, place than that? Just curious where you all are hooking it up to. Thanks in advance

I run multiple grounding points.
1) main negative to the frame itself
2) from the frame to the alternator
3) back of the block to the fire wall (grounding the Body)
4) underneath the rear of the body to the frame
having so many grounding points to has ensured that I never have grounding issues.
I also make my oan cables out of 00 welding cables

I do 3 as well. My main go to front pass side intake manifold bolt, 4 ga.
8 ga to frame, and 10ga to core support. Plus I have braided strap from valve cover to firewall.

I have used the alternator bracket and I also have bolted to the head.
I always complete with engine to frame and frame to body

Thanks for the help guys!

Not directly answering your question, but this is one way I distribute my ground connections:
I use this Bus-Bar to connect all the ground for the EFI etc.
I have the heavy gauge wire from Battery to a front lug on my engine block. From that, I run the negative cable with the Green heat shrink to this bus bar. The one with the Blue heat shrink goes to a spot on the intake manifold.

That’s a good way to add extra grounds!

Bad ground connections will wreak havoc on your EFI system. All the sensors are dependent on good ground for their readings. The way I did it, I can easily keep an eye on the connections and not worry about any corrosion at different points on the block. There is good redundancy with the heavier gauge wires going to the block and intake manifold separately.

A little late to the party, but I did mine in a similar fashion, but using an aftermarket marine fusebox that had both positive and ground spots. A lot of electronics want the ground and power to come from the same source, and multiple ground points help minimize voltage differences at different locations on the vehicle, giving a more accurate reading for those of us who don't follow the instructions and put a ground wire next to every sensor. I also run a OO to the frame, block and body from each battery, and an 8 ga from the block to the heads on each side. As several have said, having insufficient grounds can drive you crazy with intermittent problems and mystery issues that seem to have no cure. Ground as much as you can, and remember the grounds should be the same gauge as the hot wires!
