I popped the loom out from the inside...it helps to set about the area of fuse box with an angle grinder to enlarge the hole...then the whole lot will pull through...the ecu has a 10mm bolt through the connector which needs undone to allow it to come out...cant help with your connector but doubt it will stop anything from running possibly fuel rail temp sender ? but dont take that as gospel..the other part in the second pick is tied into the same part of the loom as the ignition amplifier have a look at this site
