Are you referring to the indicator light on the cluster that shows the top is not fully repositioned?
On the 2004 models there is a small three pin wire connection that goes to the convertible top transmission on the left side. Jumping the brown and brown/black wires should make it indicate the top is closed.
See my posts in this thread for pics and more detail:
Stuck Convertible Top - Manual operation...
Also, consider removing the relay for the top... I think that works too.
