I'm building an RV-9A with an Eggenfellner Subaru E6 engine. I will be mounting my batteries in the tailcone of the AC, and will have to route the power cables (probably two #6 wire size with terminals) fwd to the firewall. Since I have an all metal AC, how do I terminate this large cable on the firewall (aft side), with connecting cables, going fwd to the starter and also to the instr panel? Haven't been able to find any type of an insulated standoff for this. Can you recommend something?
Also, where can I get a schematic for the Wig-Wag circuit so I can interface to it? [quote][b]

That looks just like the one I bought from West Marine. Probably cheaper too.
Once fat wire was connected to above “pass through terminal” at the firewall I branched off to a four pole bus bar like this: http://bluesea.com/category/9/35/products/2307
From here I fed the Egg. “Master Switch” with a #10 wire, and the main fuse block (or a Vertical Power box) with a #6 wire.
I used a #4 “fat” wire and lugs from here: http://www.periheliondesign.com/fatwires.htm
And only one fat wire from rear mounted batteries to the firewall in my RV7/Egg E6Ti per Bob N’s Z19RB,
Then a #10 always hot wire from “Engine” battery to the Egg. “Master switch”, emergency side per (Jan Eggenfellner).
Also one #6 from rear mounted batteries ground lug all the way through the firewall to an engine lug (per Jan).

That particular Terminal Feed Through Connector is only rated 250A (at)48VDC. You would probably be better served purchasing the 400A (at)48VDC version from Blue Sea Systems.
http://bluesea.com/products/2206
They also carry both Black and Red and they are identical to the ones on Ebay except in a larger amperage rating and slightly larger physical size. I wouldn’t be surprised if they were cheaper from Blue Sky either. $11/each seems kinda pricey to me.

I have no personal knowledge of that except to say that the original design
was for a marine application. You would probably be best served by
contacting your local Blue Sea distributor and asking them for complete
product specifications. I know there is one in Bloomington.
West Marine
8537 Lyndale Avenue South
Bloomington, MN, 55420
(800) 432-7652
Give them a call
