Now in looking at the pic, the rectangle hole is for the Ebrake cable to go through and I can cut that out. The other two holes on the other side were filled in and I assume that is where the wire bundles were inserted through.
The larger square hole I am not sure but is probably where the oem fuse block was attached I am guessing so I don't need to worry about uncovering that again just yet until I figure out how my AA wiring kit is going to attach to the firewall.
As for the ECM and engine harness, we have already drilled a hole on the right side firewall for that to go through and mount the ecm on the passenger side near where the A/C system will go but not in the way.
