Never had the issue - but in a dash switch hack to hide the trunk open button I can say that the light blue wire in the connector is the trunk opener. I posted this project a while back -->>Trunk Button Relocate. Here's a picture of the plug that you can get to by opening up the dash end and doing a reach around to un plug the button (and a few other controls on that harness I suppose). Light blue wire to ground pops the trunk.
