How do you change the computer on a 1993 Honda Accord?

locate the computer...usually under the passenger seat...disconnect the battery's possative cable...remove the seat if required...remove the 2-3 plugs from the computer...un-bolt computer from floor...take the computer w/ you to your parts house because there is a HUGE core value...Match the computers by year/make/model/engine size and reverse the proscess to install.
