Engine Wire Harness Copper Connection Location?

[LDub]

Hey guys,
I've been in the process of doing a what I call a Baseline+++, and need help remembering where the rectangular copper connection off of the main Engine Wire harness connects to? I thought I took enough photos, but I can't seem to find where it was before I took it all apart. It seems like it may have been connected to one of the bolts on the back side of the upper intake manifold or to the engine block? Is this a ground wire?
If anybody could help me out here, I'd appreciate it. Attached a photo with the connector circled.

The ground goes to the plenum.

On mine, it's the lower mounting bolt for the brace that supports the air chamber/plenum. That makes a block/head ground and not just a head ground.

Hmmm I'm missing this ground..

Get rid of that pesky heater hose while you are in that deep!

Here's the new phh installed (with some other hose upgrades too). Yes, I put the clamps on later on. Thanks everybody for the replies. I'll post an updated pic of what everything looks like now here in a few.

This is what it looked like when I first purchased it.
