I'm looking for some input on what you guys have used for your firewall pass through's for wiring, throttle cables, heater hoses, etc. grommets seem like a problem waiting to happen!!

Have a look at these items.
We have been using the Hubbell cord connectors (strain relief). They come in a variety of sizes and work very well for firewall penetrations. We have been using them for over 10 years to run control cables and wires through the pressurized firewalls of Lancair aircraft.
We have been using the aluminum ones but they do make them in stainless also.
Here is what they look like installed. I am quite happy with how sturdy they are. For the fat hot wire to the starter they even have a non-cunductive grommet that works well. These guys provide quick service and you can tell them exactly how big of diameter pass-thru you want. http://www.azshowersolutions.com/Engine13.html

I'm curious about where most builders of the newest series of Kitfox are locating the firewall penetration for most of the sensor and other wires coming from the engine and firewall forward. My firewall came with a pre-made hole in the upper left area that I'm not sure I want to use. I'm also considering a nice multi-pin AMP connector for that job. There is another existing hole on the right side that I assume is for the main large wire from the battery/solenoid going to the cockpit.

John,
I used the pre-made hole in the upper left for the engine generator wires. The pre-made hole in the lower right I used for all the engine sensor, ignition, battery, etc. wires. In fact it was not large enough for all these so I punched another one just above it (I thought that was better than enlarging the one hole).
