I just unhooked mine last night....it is under the right cover, I will look at what sleeve it is in, and get back to you.
Alrighty, the intercom wire should have a red connector on it. The sleeve that the other side of the plug is in is black. It happened to be directly behind the large clear sleeve. There are a few other wires in it, but I don't happen to know what they are for at the moment.
Hope that helps.
