yea, i have a 200 si dash conversion in a 96 hatchback...i bought the shell like that and put a b16a2 motor inthe 2000 si harness but the heat doesn't work...i don't believe there's any electric going to it because when heat buttons are pushed, they don't light up. i was told that the reason the heat doesn't work is because some kinda of extra wite has to be wired into the si harness from the dash to work...i'm just hoping the core and everything is in there...is there anyone with the similar work done or know how to solve my problem before i spend a fortune getting someone to diagnos it? thanks.
