I had the same problem. I called Lightspeed and they said you must make a hole large enough to push the connector through. That was after I had already cut the connector off. I bought a new solder cup connector and remade it - that was a major project! There is no easy answer but I think you will have to find a way to get their connector through the firewall.

I bought a 1-1/4" SCAT tube flange and drilled the hole just
slightly larger than that, so there's no sharp edge for the
wire to touch. Then I took the shroud off and ran it through,
along with all my EIS probe wires and most everything that
goes thru the firewall (with sum exceptions). I stuffed it
with fire putty, and capped the ends with RTV.
The exceptions were the big fat wires for the charging system
and the 3 coil wires for the lightspeed. The coil wires I used
1 eyeball drilled to size to hold all 3 wires, and then filled
the gaps with hi-temp RTV too. I think I also ran my
mag P-lead and fuel/oil pressure wires through elsewhere too,
just for convenience, but they could have gone through the same
fat scat tube connection.
It's kind of a middle of the road approach. There are some
who will use snap bushings everywhere, but I think that's maybe
a little far on the liberal end from a safety perspective.
There are some who will go with the all-stainless fire-sleeved
passthrough stuff, which is very respectably on the far end of
the conservative safety end. But, you're allowed to pick your
method of choice.

Cut the cable and solder a new connector on. Not hard and you don't end up with a huge hole in your firewall to fix when something better than Klaus' product becomes available.

I used 1" stainless steel firewall penetration seals. I only had to file the hole slightly larger than I was originally planning to allow the connector to pass through. Pictures attached.

Very nice Jim, you should name your supplier.

I purchased the SS penetration seals and SS heater control valves from:
http://www.epm-avcorp.com/tubeseal.html
By the way, speaking of the heater... Except for the SS heater control valves, I built my heater system per the plans. I went cross country with my RV-10 and a friend in his Piper Warrior last month up to Maine. It was around 15-20F on the ground that day. Other performance issues aside, the RV-10 heater kept my rear seat passengers very comfortable at 9,500'. In contrast, the passengers in the back of the Warrior were quite cold after the 1.5 hour flight. In fact a water bottle left on the floor in the back of the Warrior had frozen. One more reason I love my RV-10.
