ICC remove/instal questions

[dddp]

Anyone able to tell me what this "Before attempting to reinstall the ICC unit ensure that the multi pin connector is pulled forward (toward the rear of the vehicle) until an audible click is heard. This resets the connector and allows for easy reinstallation." means from the bottom of this page

Is the the multi pin connector an audio connector or something?

Also, is the ICC must be kept upright thing a myth or is it fact? Can't see how ICCs could be posted if they have to be kept upright all the time. ICC in question is the Fairmont one, though i imagine they would all be the same apart from the different hardware in them.
