You need to get two wiring harnesses made by Metra electronics. You can probably get these at Circuit City or Best Buy:

METRA 70-1721 - to plug into the the Accords wiring harness
METRA 71-1720 - to plug into the Integra radio

Once you get the wiring harnesses, just match up the correct wires and it should work. I would try mounting the Integra radio first to make sure it mounts nicely(which it should).
