I had the same problem with my '04, probably because it was the first time the hard top was coming off.
Try pushing the plugs in on each other a tiny bit further. Your goal is to relieve the stress on the latch where it catches the hook. Then, gently push up on the latch. If you need to, try using a stubby flat head screwdriver, applying gradual pressure for a few seconds.
After that, try pulling the plugs apart with two slip joint pliers. Give just enough force on the pliers so you can get a firm grip on the plugs without feeling like you're going to crack them under the pressure.
It may help to repeat the process a couple times to loosen up the connection.
If it's totally screwed, you could always order another wiring set. Those tend to be kind of expensive, though.
