Hi, our latast aquisition, 89 8v digi, has two alarm/immobiliser systems, both working it seems

Anyhow, one is a Clifford Concept 100 and the other a Meta M36T2. While under the dash looking at the MFA connector yesterday I found black and blue boxes dangling in there, just wondered what they might be for, perhaps to do with the alarms? Can't find anything like them on the 91 car.
In the last pic there is a loose connector with 77 on it, just wonder what that is for? (note missing clutch pedal stop?)
