How do you go thru firewall

[fupo1]

With the 03-05 Corolla i have only found one grommet in the firewall to allow user to feed lines or cables from the engine area into the inside cabin. The grommet is about 1cm. 

 

Is is this the only hole for users to get things through into the cabin?

 

i have already filled that hole and have more accessories to patch thru to the inside of the car. Any thoughts

use the kick panel grommets.

Thanks so much. Never thought of or knew that the kick panels have access holes leading thru to the engine bay. Great!

knowing that, it would have made more sense to feed thru there the variety of lines I got, vacuum, power, switch
