No matter how hard I tried, I missed some wire connections.  The first was from the negative battery cable to a ground under the block on the driver’s side.  Also grounded to the same place was a branch from the bunch of wires (from an earlier video) that went along the bottom of the timing cover and the front of the oil pan. These wires are actually the ones that go to the starter.  They are affixed to the block on the passenger side and needed to be separated.

Then, there’s the branch that breaks off at the top of the firewall near the AC accumulator.  It dips down the firewall and disappears along the frame.  It eventually goes to the passenger side O2 sensors.  It’s a long sucker with several fix points, but I wanted it out of the way for engine removal.

None of it is hard to do, it’s just that it seems like GM used a wide variety of connections and retainers.  I had to go slow and make sure I didn’t lose my temper and just pull the connections apart.

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.
