Connector Stability

I just completed my Flightbox and EMS install, and during my last runup test, 2 Ferrules (Fuel and MAP) came loose from the socket. This, on top of getting the crimps right, seems a bit frustrating. I used the e1008 1.0mm. Is that the correct size for the connectors on the EMS? I didn’t see a size referenced in the install guide.
