Do you have a 4dr??? Was it a pain to remove the headliner???Take off the little cover on the map lights on the headliner, it is a small square on the plastic. Inside you will see a hole that looks like it would be for an allen key. I dont know what tool you need, but Im sure you could get it from Acura.
Sorry I didnt answer this sooner, I had an idea of where it was, but removing my headliner last night reminded me of this thread. Good luck.
