My high-temp grommets arrived from McMaster-Carr. Checking the fit on the fuel supply hose...
...and the return line. Perfect!
These are the parts I got.
Bought some threaded rod to use for the grounding bolt through the firewall.

Just a few minutes tonight bringing in some new parts and checking a couple of things.

1 hr. on the firewall.
The ANL fuse is going here. The right side connects to the shunt and the left side will connect to the 22,000uF Cap and External Alternator B+. I considered putting it further up the firewall, but it would be difficult to get to the backside further down the road if the need arose. There's also a strengthening crossbeam on the cabin-side above this area, so it would have to go much further up to clear that.
I'm thinking the shunt (which strangely hasn't arrived from SteinAir, so is represented here by the white rectangle) will go under the ANL fuse. The left side of the shunt will connect to the left side of the Master Relay (see on the left side of the photo) and the right side will connect to the ANL terminal just above it.
The ground of the battery will connect as shown.

4 hrs. on the firewall.
M5 rubber mounts in (medium Loctite applied). I'm going to put washers/nuts on the backside too.
Playing with placement of the Master. Decided to go lower than this to keep away from the harness of the TCU. There's a good amount of room though for the harness due to the spacing of the TCU off the firewall...
As you can see here. I was going to mount the master sideways, but the part installation instructions specifically state to install it with the cap down. So, down it went!
Friend Kerry helping out. Thanks Kerry!
Bolted in!
Battery in too.
Close up of how the diode is attached in the starter solenoid. Used this to enable connecting two spade connectors. The other connection goes to the starter key.
Getting there!

2 hrs. drawing up the firewall electrical power wiring.
After consulting The Aircraft Wiring Guide I slightly modified the location of the shunt and drew up the power circuit.
From the book. While it says the VPX measures all the currents, it doesn't measure battery charging/discharging, so I will add shunt "C" in this diagram.
Considering the diagram from SteinAir and the above, I drew up the following diagram which shows my plan for the relative placements of the parts on the firewall.

Got confirmation on how to connect up an ammeter shunt so my battery charging status can be displayed on the G3X.
From SteinAir:
You can add a shunt on the output side (the side connecting to the system, not the battery terminal) of the master relay and then connect two wires from the small terminals on the shunt to pins 36 and 37 on the GEA24 J243. Then go into the config mode and in the Engine and Airframe section, change shunt 1 to read Battery Amps. This will now display amps on the G3X.

This is the recommended shunt, which I just ordered.

Well, I've wanted to work on the plane.... But, a work "emergency" and home tasks (have to keep the spouse happy if you want to complete an airplane... ;-)) have gotten in the way of progress.
My plan though is draw up a complete layout of the firewall (which I'll share here and on the Firewall Page) so I know where everything electrical is going to go. I need a complete plan to make progress on anything.
On the suggestion of someone on the Sling Builder's FB group I'm going to add an External Ammeter Shunt to my circuit so I can better monitor my battery status. It's a very easy add and I'll share those details when I'm completely certain of the implementation.

Heads up!
I recently bought some Loctite 277 on Amazon... I'm not sure why, but the labels just struck me as a bit suspicious. So, I contacted Henkel directly....
...and sent them pictures of all the surfaces of the bottle....
Batch code...
After a week of research on their part: COUNTERFEIT!!
Henkel:
"The label lists “Made in USA” but uses the batch code system from the China plant (MT83727399)." and then in a subsequent email: "Confirmed counterfeit. The batch code doesn’t exist in our system."
Wow. Back to Amazon it goes!
