Hello

Just bought a new house and it seems the previous owners tenants have taken the ONT power cable with them.  Looks like an 8 Pin Molex connector.  Are these easy to get a hold of? 

I had an email through on Thursday 6/7/17 advising that it's "almost the big day" for my fibre connection scheduled for 6/7/17, and that i should receive a phone call from a technician which never happened so I can only assume that the install was done remotely due to the pre-existing ONT/ETP?
