d16a6 swap to d16y8

What up, yalls! I know this thread has been discussed before, but I may need a little help... I am pickin up a complete d16y8 with axles, tranny, & harness tomorrow. What exactly do I need to do to get this little monster roarin? How do I get the Vtec to engage? I currently have a d16a6 with an Si tranny. Any info is most helpful, thanks!
