I hope you guys both saw that I posted a link to a gsr harness on ebay in my last post.

To explain what I meant before..

1. unplug both harnesses he has - leave the engine bay side of cx harness hanging in engine bay.
2. drop in b18c, sans harness
3. start plugging in, lengthen or add as needed (which will probably be a bunch with dohc teg --> sohc civic swap).

When I swapped a b18a into a 91 civic hatch, I used a foreign harness and with all the troubles, I swore I'd never do it that way again. I found myself wishing I'd left the stock harness over and over again. I got tangled up a lot in the under-dash portion of the harness and screwed up all kinds of things that way.. odo, speedo, etc.
