Holes in Firewall ???

[71Demon340]

Can someone tell me what goes where as far as the holes on the driver side firewall on my 71 Demon. I'm pretty sure top left is speedo cable. Mid left is brake booster and linkage. Bottom left is steering colum. What are the three holes on the right side? I know one has to be the parking brake cable. What are the other two. Also, where would be a good place to drill a hole to route the battery cable for my relocation kit. Well I was ready to attach a pic, but won't work for some reason. Added a pic of firewall to my gallery. Thanks.

one of the holes was used for foot pump window washer, otherwise plugged. Another hole was used for remote hood release, oterwise plugged. I dont recall exactly which is which.
