Wires and harnesses.  There are a few kinds on modern engines.  The ones you can see, and can get to; the ones you have no clue how to get to; and the ones you don’t know even exist yet. This video only tackles the first type, the easy ones.

They’re there, in plain sight – and relatively easy to get to and remove.  If you are gonna pull the block, they need to get unhooked.  Firewall ground straps are fairly straight forward.  I chased a part of the harness to the mass air flow sensor only to realize that it branched off (near the AC accumulator) and down the firewall, along the frame, and out of sight.  I decided to figure this one out in a later video – as well as another ground under the block that I didn’t even know existed until later.

So many wires and harnesses, and these are the ones you can actually see on a GM 5.3 Vortec LS Engine

Aside from removing the grounds near the firewall, this video is a bit of a lead down a dead end road, but this is a documentary of my journey, so I left in the dead end chase as well as when I got it right.
