ok i have a 91 civic si hatch and i recently ordered a b16a1 w/ cable tranny harness, ecu, and shift linkage... well i've been reading around. and i was wondering if you have the stock b16 harness can you just use that w/ out rewireing much of anything but the dash or do i have to get a harness conversion from hasport doesn't really matter it's only 75$. but what other install problems should i expect. how direct is this bolt in... i've done a sr20det in my s13 so it should be easier than that right. that was pretty easy.
