Returning to the OP's question - I had to get a bigger piece of fire sleeve than what was provided in the kit to do the outer "wrap". I had some laying around fortunately.

Like others have said, for single cables use the steel multi piece eyeball pass through?s mentioned above. Harder to install but worth it! The single hole aluminum ones are junk!
As for wires/bundles you can get all the parts to build them yourself way cheaper if you buy the parts to make it individually. You can buy the stainless flange from hardware stores or amazon. Look for stainless closet rod holders. They are less than $10 for a pair of them.
I did not do this on my 7 but will on my 10!

which size?
I see on Amazon there are different sizes of these stainless rod holders. Is the 1 inch diameter big enough if using 2 of them? I think the other is 1.3 inches inside diameter. Is this like anything else where bigger is better?

I had the same concerns about the firewall sleeves and had it confirmed by Vans that we use the FAE102-11x1 ft sleeve they send with firewall forward kit. Apparantly we make that fit for both the inner and outer pass through by splitting that sleeve.

How many
I have a large one and a small one. The large one was required to pass the EFII harness connectors through. I separated the EGT/CHT wires to the small one, as was recommended by Garmin.
I now have a System 32 EFII harness which includes bulkhead connectors so I really did not require the large pass through, 2-1" pass throughs would have been sufficient.

1st, decide whether you need to pull assembled connectors or control cables through the hole(s). If yes, then the connectors/cable ends will define hole size. Bundle up everything you need to run through each hole, wrap the firesleeve, and measure.

I am debating adding a few extra pass throughs. An A&P suggested that all the cables go through individual eyeball fittings, then the wires can run through the two original pass thru locations. Anybody do this? If so, then where did you place the eyeball fittings.
I did purchase pass through kits from ACS to bundle and protect the wires after coming through the firewall.
Unfortunately, I just finished insulating the firewall, so putting in eyeball fittings might be a nightmare. I have the insulation and the engine mount in place. The though of all the shavings from drilling make me sick to think about cleaning up.
Thanks

I just purchased this hydraulic punch set from Amazon Aircraft Stuff. Tool quality is basic HF/Chinese but it makes an easy and clean punch thru the SS firewall.

Any thoughts about using something like the aluminum bulkhead in the link below as a pass thru for the cable, if it were made out of stainless steel? It would not allow for rotation like an eyeball fitting, but it would require a much smaller hole in the firewall.
