Hey guys, I'm trying to install a Vintage Air in my 67 Camaro and wanted to do something alittle different from what the instructions mention. I want to run the wires through this hole(the one with yellow tape), but I'm not sure what it was used for originally. I looked at the original heater box and the studs don't go through this hole. The hole in the picture(marked with yellow tape) is where I want to running the wires. Does anyone know what this hole was used for? Maybe to fasten the firewall pad?

Thanks,

that would be my guess although the heater box does that as well

Not sure but I have the same hole in my 68. I ran the a 4 gauge wire to the trunk via that hole. Make sure you use a rubber grommet!

Firewall pad grommet, I used that hole for my amp power line
