What year is your Integra?

If it's a 94-01 2dr, here's the deal.

From the rear of the car, remove the plastic interior trim piece that forms the back wall of the trunk. Then, with the rear seats folded forward, remove the connectors that hold the driver's side rear trim panel in place (Theres a bolt underneath the shock tower cover panel as well).

Once the connectors are out, carefully pry the side trim panel loose. You may need to disconnect the harness for the trunk light in order to have enough room to work.

Then, once you can reach the base of the antenna, unplug the clip-type harness from the motor body, leaving the heavy gauge, black antenna wire plugged in.

Secure the motor harness plug so it won't rattle or short out to the body.
Reconnect the trunk light harness, replace the trim panels and you're done.
