Inline 6 300 engine grounding points.

Can some one guide me in the right direction for all the engine ground points on an 87 f250 inline 6 300? Also isn’t there a thread or something for upgrading those points?

One between the battery and radiator support on the inner fender. One on the passenger firewall next to the hood hinge. That cable runs back to the intake, and the other to the hood. One on the lower right hand stud/nut holding the wiper motor on. One on the drivers side fender at the rear, facing the brake booster.

The battery ground cable grounds to the frame and engine as it makes it way to the starter. There is also a cab to frame ground under the drivers floorboard. This clips on.

One on the metal fuse panel at the rear. Lay on your back in the floor, and looking up, you will see a screw with two wires.

There are rumors of a stud behind the radio, in the firewall. I have never seen it, so I don't know.

Some newer models of this same style truck have grounds behind each kick panel, next to the floor. Mine doesn't have these. Might be an '87 thing not to have them.
