Hyper Ground/ Earthing kit ground points
1) battery to chassis ground (opposite the battery... Also, covers 1 of the big 3)
2) battery to intake manifold
3) intake manifold to opposite side of the engine head (in the front)
4) from the engine head to the tranny
5) from the engine head back to the battery

It's one big daisy chain. 6/8 AWG power wire should suffice...

While you're at it... You might as well address the Big 3 just in case you have dimming lights whenever your bass hits HARD.
1) #1 from above
2) engine to chassis ground
3) alternator to battery cable run
