Firewall!!

[mikeukrainetz]

Ive posted a whole how to on Yarisowners.com (probably the same thread that was mentioned earlier).
I have now posted photos as well, some supplementary info if you will.

Drilling the hole in the firewall was simple, didnt take much time, easy access and provided a good location for access to the battery and door sills without sacrificing an extra three or four feet of cable.

See the post it may or may not answer your questions but it may help.
