I ran mine inside as well using a bulk head to pass thru into the engine compartment. On a First Gen there's a nice little ledge that seems perfect for running the cables and bulkhead. I admittedly stole the idea for mine from pics on DSE's project updates page!
Agree with all above
I ran my 1/0 “navy strand” cables inside under carpeting along outer edge on passenger side and grommeted firewall at starter location.
Curious if you are running fuel injection?
If you are, try to keep your EMF sensitive fuel injection wiring to the battery separated from other wiring.
You can hit the "you pull-it" junk yard and grab the LX cars' battery bulkhead connector in the passenger footwell. Super nice, high current, OE quality piece. If your feeling extra energetic, pull out the cable while your at it. It's a high quality cable and ends you can get for next to nothing.
