2004 explorer V6 4.0 engine block ground wire

[04exp212s]

I'll make it short... Been searching around, and just can't find the engine block ground wire that I need to upgrade for the big three... Has anyone done the big three on the 04 that could help point me in the right direction?

Just follow the ground from the battery back to the engine, lol.

Can't be too hard.

battery to the bottom stater bolt, firewall to rear or side of passenger cylinder head
