Best Place To Go Through Firewall

[LSWHAT??]

Does anyone have a specific place that they run wires/braided line through the firewall? I need a hole about 1/2" diameter, and wanted to know if there are any plugs or spots I can go through without drilling through the wall.

Thanks

I ran a wire (water temp) below and to the right of where the clutch cable goes throught the firewall. There's a spot where Ford ran a bunch of wires through rubber boot in a single tube. The rubber boot is great cause it seals it up and wont cut the wires.
