I bought a used telematics module off eBay (supposedly for my 2012 Dodge Journey), installed it but it didn't rectify my no connection issue. I didn't mount it in place, could this be the reason it still doesn't connect? There is an "integral locating pin" on the mounting case, should I have mounted the module before testing it? I just left it hanging by the connectors while I tested if it connected or not. See item #1 in attached photo. What does this "Intergral Locating Pin" do? Does this pin close a switch or something?
