Speed Hut Gauge Wire Routing

[starnsey]

How do most of you guys route the wires for Speed Hut gauges? I've got oil pressure and water temperature and previously just had them going through the hole where the main large grommet is above the pedals, but eventually they would inevitably rub through on the firewall sheet metal. Is there some way to put them inside the grommet? This would obviously require cutting the grommet, but how would you even do that? The water temp gauge wire has a large connector that couldn't just be shoved through the grommet.

Or if y'all did something different, I'd like to see that as well.

I used a razor blade to cut a slit in that grommet then fed the wires through. None of my plugs were that big though. You could always get a hole saw big enough for the water gauge plug and then use a body grommet to seal it. I've seen those at parts stores. You'd just have to be careful where you drill.
