I have a complete 92 civic dx that I'm pulling the drivetrain out of to swap into a dune buggy. What is the bare minimum I need to make it run properly as a stand alone engine and auto tranny? Can I Hotwire stuff like auto shifter safety switch? Can I use basic relays to power the computer, fuel pump, etc? What can I get rid of from the harness that is not essential for proper running?

How about a link for d15b7 swap into any non-Honda vehicle?
